(action) when somebody with large hands shoves their thumb into a males asshole and then using their large hand punching the balls with the remaining knuckles. Pop because the person pops the males asshole and lock because you lock in the fact that they will be scarred for life
Albert got the Pop and lock at the party last night, he lost his anal virginity and suffered testicular damage.
