A gesture often done in night club environments by girls to entice men and to simulate what will ensue in bed if you got with them.
"Oh man, you should have seen how she was grinding against his cock after that"
"We know that he's obviously getting some"
I'm Russia a group of elderly men and women sit around a broken refrigerator. They all have a nice cup of warm twerk. The first one to finish gets another cup of twerk and the cycle keeps going on until the pot of twerk is gone. The person who gets the last bowl of twerk gets to use the bathroom first. This ritual is repeated every 2nd Sunday.
Okay do you have the broken refrigerator?
