rotating your beer bottle (or other alcoholic drinks) in order to create an angular momentum for the particles of the liquid which makes it easier to drink the liquid fast
Hey bro, you should really swirl that beer!
Damn, i feel like swirling a bigbottle of Heineken right now
Do you even swirl, bro?
It's when you shit and cum at the same time while wearing underwear. Similar to soft serve ice cream swirl which has both chocolate and vanilla softy serve on the cone.
I just swirled myself after eating taco bell and watching the newBelle Delphine sex tape.
