The act of pulling out your manhood and beating it against something to give a flesh-on-flesh slapping sound. It can be something of yours (leg, stomach), someone else (girlfriend's face) or an inanimate object (getting it out in the pub and Wapping it out onto the table)
I was running to answer the phone after having just got out the shower and gave myself a nasty case of cocklash.
