Beatin Cheeks 

Any sexual activity that results in skin clapping and flopping around. Primarily but not limited to balls banging against ass.

Do hear that? Sounds like they are beatin cheeks in the room next door.

Man that Chet fella is a real cheek beater, everytime I talk to him I can hear beating cheeks.

beating cheeks

(as in a jockey, beating the "cheeks" of his horse to make it run faster)

To be in a rush. To go —especially, to walk— very quickly.

"Sorry I'm late. I beat-cheeks to get here on time".

"John got a speeding ticket today. He was beating cheeks to get to the airport when he got pulled over".
