When a man's cock accidently slips out of whatever he's fucking. Can happen if he misjudges his stroke, if his partner is too loose or wet, if his cock is short, or if he is unfamiliar with a position (usually doggy-style).
That girl was wide open, man. Way too much slippage, and right when I was 'bout to bust. (Note: Generally not a word used in normal conversation. 'Slip' would be the most commonly used variant.)

When a woman is on her period and her poopy is all slippery and runny and messy. No effort to move the bowels is required, the poop just "slips" out.
Sorry I couldn't hang around. This damn slippage is keepin' me on the poop tank all day
