What is soundcheck?

When you're fucking a deaf chick from behind and you scream racist insults directly into her ears.

I was soundchecking an Iranian carbomb survivor and I woke up the neighbor.

When you slap your dick against her pussy before putting it in.

Her: Why did you slap my pussy last night before you f*cked me
Him: soundcheck babe

Making sure your sound is on point before you do a show. Faith Evans always do a soundcheck, about an hour before people come to watch her perform.

I'm getting ready to do a show. Are you guys ready for soundcheck, before it's time to hit the stage?
