Cock Slap

v.kok slap. The use of a man's penis(cock) as a weapon to slap the shit out of his girlfriend/wife/boyfriend(if your queer) when frustrated with them.

1. I told my girlfriend to make me a chicken sandwich, and she didn't so I Cock Slapped the bitch!

2. While my wife was giving me a blow job, I decided to pull back and Cock Slap her for fun.

3. My boyfriend told me that that we didn't have any KY Jelly left so what did I say, "Boy go buy that Jelly, and when you get home be prepared for a ruthless Cock Slapping".

Meat Slap 

The act of slapping a piece of red meat as hard as physically possible. A test of how good a piece of meat is, usually performed in ASDA. The louder the noise, the better meat quality. If the slap is pitiful, then the meat is off/not of decent quality, and should not be bought.

Don't buy that gammon, it sounded shit when I gave it a meat slap
