Generally used to descibe someone with the tendency to copy; used especially in states like Massachusetts and Connecticut. Basically, if you lack creativity and a unique sense of style, copying ones image will most likely take place. This may range from biting ones shoes, to girlfriends/boyfiends.
Dude, did you see Chris today? He was totally wearing the same shirt you bought like, 2 days ago. What a biter...
Used to block out any gay energy when a guy does something completely homoerotic to another guy. Usually the banter is playful, while the boys engaging know each other very well. In a typical situation, the guys might get excited over a sports event, or more commonly, a videogame, and jump all over each other.
What, your shoulders hurt? Hm, well I'll give you a massage dude, but no homo!
