a spank - Getting your butt slapped so hard it feels like your pants a

Getting your butt slapped so hard it feels like your pants are on fire. It starts with tight pants, ends with no pants and a very sore butt.

A spank is when your ass gets smacked so hard it feels like the heat death of the universe and you want to rip off your pants while screaming.

My mom spanked me after I broke my phone.

I got a spanking for eating my lunch in class.

My dad gave me a spanking for not doing my math homework.
