sex proper 

Though sex can be considered the whole period of time between the beginning of foreplay and the end of cuddling, sex proper is the time between the entry of the penis and its removal.

The important thing to remember about sex proper is that its time of entry that matters, not place of entry.

Poopersede 

1. The act of one's stink in a public bathroom being overridden by the next guy to take a dump.

2. To have another's dump cover the fact that you stunk up the restroom.

3. When someone comes into the restroom to take a shit just as you're wiping.

Broski: Dude, I had Chile con Carne last night and completely blew up the mens room next to the boss' office just now.

Dudemeister: I can never dump at work. I'm too worried everyone will know how foul my shits are.

Broski: Yeah I normally have the same problem but as I was finishing up, Jeff went into the stall next to me.

Dudemeister: That's lucky. Jeff's fat dump is going to totally poopersede your foulness.

Broski: Yeah, and I've been nailing his wife!
