When you have a quiet night in, buy a 21 piece bucket of KFC chicken, smash it while watching some porn, then use the left over chicken grease as lubricant to pleasure yourself.

I recommend putting a towel down while having a grease beat and please ensure a hefty clean up after the experience.
"What are you up to tonight, mate?"
"Heading home early for a major grease beat session"

OR

That guy has a grease beat 2-3 times a week
