When the male is long stroking and has a great rhythm but his "member" slips out and rams the woman's genitals. Often times painful

A moment or surprise as you fall over and somehow land inside a woman. Although it was an accident you play it off as it was on purpose and impress the lady. Not many men can pull this off but if you can you must be very tactical.
Girl:"hey, babe im ready..."
Man:"Im coming babe*slips over(tactical slip)"
Girl:"Wow you're so trained, you must have done this before"

When attempting to whisper in a chat room and inadvertently posting to the whole room, or worse global.
Lucan let out a whisper slip, and Seph never let him live it down. We now know everything that goes on between them.

Forgetting to zip back up after going to the bathroom in a public place. Often accompanied by a "zipper coma", where you almost NEVER remember to attend to that little matter.
Of all the times to do this, Fred had a zipper slip just before walking up the aisle at his own wedding.

To have sex while behind a girl in her anus. Usually at a pool party when you pull the bikini bottom to the side and "slip a quick one" (or a quicky).
"Your pool party was dope Billy, I slipped 3 quick ones on Marge!" You should go slip a quickone on your girlfriend Heather!"
