an acronym used to as a quick comeback. It stands for "Your Mom Adores Cock". Many people have never heard of it, but it is quickly making its way around in the lingo of everyday teenagers. Also, it isn't spelled out when said, "Y-M-A-C", instead it is used as a single word with the "Y" kept out, "Y-MAC".

A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.
