a term used by "Snookie", a co-star of the popular ( in 2010 ) MTV reality TV show 'Jersey Shore'. "Gorilla" refers to a big, muscular guy, and "juice head" refers to steroid use (juice is the street name for steroids). So, Snookie is always on the lookout for a 'Gorilla Juice Head' to take back to the MTV Jersey Shore home, even if it is being filmed, to have casual, one night stand sex with.
Interestingly, she wants a well built, tan, good looking guy, yet she happens to be a chunky, unattractive little dwarf -- something you would normally see at a carnival freak show at the turn of the century
