Apparently somewhat on the fringe in gay circles, but involves using thin, cylindrical items (thermometers, wire, rubber worms, etc.), and inserting them into the dick hole. Over many months, continue to gradually ream out the hole-at-the-head with larger items, thus ultimately allowing your "buddy" to obtain the goal of fucking your urethra. Wow!
Unexplained phenomena your ex-boyfriend does in an ill fated bid to win you back. Usually involves a lobe taper and the lubricant he uses to masturbate, to which he inserts into his urethra. The element of surprise oftentimes disallows the lube. May indicate possible homosexual tendencies. Can be strangely fascinating for some people.

ex-GF: no prob, bye
ex-BF: so are you seeing anyone? *poor attempt at cock stuffing accompanied with clumsy stroking*
ex-GF: not cool. *swallows vomit*
