What slang do you use for the term mastrubation?

I live in England and for some god awful reason everyone refers to mastrubation ask wanking-(ie you might use it like "this room stinks of wank" or "I wanked for ages yesterday") and idk how this became a part of our vocab but it's only hitting me now how weird it sounds now I'm surrounded but eve users who don't live in the uk

what do the non English people of events refer to it as?
