Hole in one

While jacking off you Jim into your belly button first.

Dave: I got a hole in one last night
John: Nice, we should go golfing sometime
Dave: oh I don’t golf.

Hole-In-One!

During sex, handjob or masturbation, the male ejaculates into his own mouth, either accidentally or purposefully.

She jerked me off so hard last night she shot a hole-in-one!
