diaper walk

Telltale sign of a male homosexual who has engaged in way too many anal encounters. The diaper walk is characterized by a slow perambulation with butt cheeks tightly clenched to ensure sphincter closure to avoid involuntary leakage. The term is derived from the fact that adult diapers are often required because normal rectal control has been compromised.

Craig: What's that oddball gait Tom is sporting on his way to the cafeteria?
Joe: Oh, that's his diaper walk from years of punching the starfish
