slouching up

1. Like slouching, but a little bit better for your posture.

2. A slightly more formal slouching technique.

1. My back's been killing me for the last couple of days. I need to start slouching up or I'm going to turn into a hunchback.

2. I was practically asleep at work the other day when my boss walked by. Thank god I was slouching up.

when you masturbate without porn and someone walks in so you put your dick inside your pants while your cumming. The person then sees an expanding wet spot on your crotch. The excuse that follows is called slucking.

Person 1:Dude my mom walking n on me beatin my meat so I said that I spilled my water

Person 2: How are you so good at slucking?

Slushing 

The act of rotating your penis inside a girl once you have ejaculated, enthusiastically, until once again erect, and repeat.

Derives from the act of mixing slush puppies with a straw to mix the flavour.

Slushing is messy!

If you don't shut up, I'm going to slush your mum all night long.
