A derogetory term for someone from Wales. Actually, the derivation of this word is as follows (from the racial slur database): "The Taff is the name of the river that runs through Cardiff, the capital of Wales. Also from a poem that starts: "Taffy was a Welshman, Taffy was a thief...." Another explanation is that Taffy is based on an English pronuciation of the common Welsh first name, "Daffyd" (David)."
Some people who is said to be a loser and fat and ugly who is a virgin. Who likes video games. People who think this are confusing with a geek. See us gamers like to have sex and to other stuff more then videogames. While geeks just want to sit on their computer or infront of a tv.
I'm a gamer. I like to play video game. I have been been with the same hott women for 5 times getting laid a lot. Geeks are people who would like to have sex with a cd drive more thena women.
