Cock Slash

When someone literally whips out his cock and slashes another person/object/animal with it. It is one of the most ridicilious ways of 'pwning' someone. Instead of saying "owned"/"pwned", you can say "Cock slashed".

Man, did you see how I 'cock slashed' that noob ?

cock n' slash

When you smack your hard penis across a girls face. This is normally a form of punishment for something they refused to do earlier.

"My girlfriend refused to go anal with me last night so I gave that bitch a cock n' slash."
