That moment when a party or tune kicks those legs into action causing your booty to thrust, fist to pump and body to get down and get on it, i.e. That OOMPFT feeling.

A beefy beat may also be described as a 'Cronker' likewise getting your groove on may be described as 'getting your cronk on'.
"That cronking bassline is making my lungs rattle"

"Dude that party last night was proper cronking"

"That last tune Buckley played was a cronker"

"Wow! You see Soul Train last night? Don Cornelius got his Cronk on!"
