A sexual act in which one man uses his erect penis to tap a second man’s testicle into a third man’s anus.

A common variant involves “removing the flag,” where a fourth man removes a dildo from the third man’s anus just as the butt-putting begins.
I thought Bruce invited me to play putt-putt golf, not butt-putt golf. That was crazy.
