what's the different between pi55ed off and pi55 off and when to use them?

Be careful with both of them. Some people find them offensive. Some people use them a lot. It really varies. I remember saying 'pi55 off' around my mother one time. She got...well...pi55ed off.  I mean that she got very angry. I have never done it since.

pi55ed off - very angry; very annoyed  (He was completely pi55ed off after his car was stolen.)

pi55 off (someone) - to make (someone) very angry and/or very annoyed;also, telling someone to 'pi55 off' is an impolite way of saying 'go away' or 'stop it' or something similar. Some people like to say this to their friends in a casual way. Some people might react like my mother. It depends.

Other people may know of different meanings, too.
