A shorter version of saying Under-alleyway; pretty much slang for the taint (which is the area between your genitals and your asshole.)
Me: "Last night I got jumped by some thugs by a goodwill and they kicked me in the Under-alley."
Friend: "Under-alley, do you mean the taint?"
Me: "No, Under-alley (-_-)."
Friend: "Under-alley, do you mean the taint?"
Me: "No, Under-alley (-_-)."
