When someone is dating someone way out of their league or is a lot younger. Comes from Adam Sandler's films where he's always with a super attractive, young women.
Doing an Adam (alternatively, "going for an Adam") refers to the act of doing a topless shit.
A topless shit is only "an Adam" if you took your clothes off before going for a shit. If you were already topless beforehand, it does not count. You must also be fully topless: no vests or bras.
Doing a naked shit is sometimes called a "full Adam", although a topless shit is never called a "half Adam".
The main advantage of doing an Adam is that when you are straining on the toilet, your shirt will not get sweaty from your exertions.
Law enforcement slang for anyone who is an asshole. This term would be used within civilians' earshot so they wouldn't know swearing was going down. In the phonetic alphabet used by police, "Adam" stands for "A" while "Henry" stands for "H". So an "Adam Henry" is the same as "AH" or "asshole."
Tell the Sergeant we have an Adam Henry here who wants to make a complaint.
