During intercourse, a man spins on top of a female while still in her, (like a breakdancer) and there's a chance his member could get stuck and twisted like a pigtail.
It's our secret , pigtail code meaning I have the greenlight to put her on knees against the wall while hanging on to her pigtails, she looking up at me while I bury it to the back of her throat....she fucking loves it!
