A frequently-used discreet
word for "masturbating". It may be used in reference to a male or female, and it also may be used when it is done by oneself or by someone else.
If you're in polite company, you would use the subtle
word "stroking" instead of the
blunt terms "masturbating" or "wanking".
Mum: Did you take Charlie his dinner?
Cheryl: No, I couldn't go in. He was
busy.
Mum: What do you
mean "
busy"? If he's busy, you can still take it in, can't you?
Cheryl: No, he needs his privacy. He was, um... busy stroking himself, Mum.
