Simlish

Simlish is the language of the Sims. Some say it may be a mixture of Ukrainian and Tagalog, but this has not been confirmed. It might be possible to understand by studying the Sims' speech in certain situations. There isn't an official Simlish dictionary, but a good dictionary is found here. It is assumed that Simlish is the official language of SimNation. Sometimes we can hear also french phrases as "bonjour".

SimCopter
SimCopter is the first game where they speak Simlish.

The Sims
This, having a lot more than SimCopter, was also a lot clearer. Common phrases "ralalalalib bubaya" and "o frazinnratt" This was created because EA couldn't change the Sims' language to the player's language due to limited budget and it will make them repetitive.

The Sims 2
The Sims 2 comes with better heard and newer phrases like "e wam". Common phrases are now "dej dej" and "ackabunad." Common greetings include "zune-zune" and "degg degg". When there's a problem, they will say "Shoo Flee" and "anaconda" a lot. When some female Sims walk by another sim, their greeting will be "Ooh, voodoo!" Sometimes they'll say "Lick a rock!". When child female sims drink juice, they sometimes say "Green iguanas fluing in the sky." They reportedly swear sometimes. Much to the amusement of many players, pregnant Sims have been known to shout "WooHoo!" while giving birth.

When female elders play at the poker table, they will usually says "Texas Goushem" which is probably a reference to Texas HoldEm (a type of poker card game).

The Sims 3
The Sims 3 has the largest Simlish vocabulary. Common phrases are "teg teg", "swebsi madoo", "madoof napso!", "abondandlain... en som?", "hubble herni", "etne condoroley","shawbo glub", "zwitz zorg", "tippaha yooredful", "shabow", "sussel!", and "ibzy biz ochoy", "ayba miyba mo!". The Sims 3 is also the first Sims game where you can adjust the Sim's voices to exactly how do you want them to sound.

Simlish Songs
The Sims 2, having many celebrity players, features many renditions of popular songs sang by the original artists. Some have music videos created by EA such as Natasha' Bedingfield's Pocketful of Sunshine, Katy Perry's Hot 'n' Cold, Datarock's Fa Fa Fa, Lily Allen's Smile, and Aly & AJ's Chemicals React. However, there are also other songs that don't feature music videos but can be found in the game.

The Veronica's When it All Falls Apart is one, together with Tata Young's Zoom. These could be found in various radio stations in the game, depending on the song's actual genre.

The Sims 2 for the PC is not the only game that features Simlish songs. Paramore's Pressure could be heard in The Sims 2 for the PS2, and various Black Eyed Peas songs are heard in The Urbz: Sims in the City, where the band is one of the prominent NPC characters found in Cosmo Street.

Gwen Stefani's 4 In the Morning, Green Day's American Idiot, and Plain White T's Our Time now are also other popular songs in Simlish.

Some of these songs are only available in Sims radio when certain expansion packs are installed. Ones with music videos often give clues to which expansion pack they are found in, such as Hot 'n' Cold (Apartment Life), Pocketful of Sunshine (Freetime), Fa Fa Fa (Freetime), and Smile (Seasons).

Spore
In other any other language version of Spore, Simlish will be spoken by Steve and 'the voice in the tunnel', which will be the same no matter what non-English language it is.

Trivia
In The Sims 3, it appears that sometimes after a romantic act, men would say "giggity", which is probably a reference to Family Guy character Glen Quagmire.
