The act of inserting a penis inside of another man's urethra for sexual pleasure.
Whenever a medical procedure is done where the patient is conscious, someone will develop a fetish for it. In the 1800s, the treatment for syphilis was mercury and urethral sounds, or large metal probes stuck up the pee hole. A few patients developed a fetish for this, and that is where 'sounding' comes from. Eventually, a gay man had a fetish for sounding, and had a partner with a needle dick. One thing leads to another, and the concept of cockstuffing was stolen from the gods.

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!

a: so what you got there sport?

b: nothing, I told you. Please go away

B: FUCK OFF!

a: I will, but I wanna know.

B: Okay, I'm cock-stuffing. Is that the answer you wanted to hear? COCK-STUFFING!

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-BF: thanks for bringing my Esteban guitar, amp and instructional dvd set
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*
