When someone suddenly clenches her/his anal/vagina so tight that you can't get your penis out again, OR your penis is so wet and sqeezy, so it will fly out like a rocket.
It occasionly leaves bruces, and maybe even scratcmarks, whether it's stuck, or if it's sqeezed out.
Oh, man! Last night Emil gave me a really Cocker Locker! I couldn't get free for like 15 minutes! I were just paralyzed in agnoy, plesure and pain!
