"I've just won £22.14 on a double in darts, I'm going to gambulate by using my winnings to bet on something that is most likely to win with a little return"
"What are you doing this weekend?"
"I'm going to watch the footy down the pub and start gambulating my winnings from last week"
"Nice one mate"
