mack 

noun: This common term can sometimes be used to describe a hard-ass individual who is constantly fighting homosexual urges, partly due to the fact that they are around members of the same sex. Some avid enthusiasts have been known to get the word "mack" tattooed somewhere on their upperbody, usually the chest.

Aaron: "Hey Eric. Did you hear about that mack Shane saying how he wanted to kiss Greg and then try to hide it by sneezing eight times in a row?"

Eric: "Eight times in a row?!"
