To "black flag".

Meaning to make a bet, and lose it. Then not follow through with the consequences.
YOU: "I'll make a bet that Carlton suck and miss the 8, loser has to suck Suzis penis."

BlackFlag: "Carlton will win the premiership you douche, i'll take your bet"

Carlton go on to stink up the entire competition, blackflag loses the bet, and ignores that the bet was ever placed. Making him a dirty welch and the lowest form of life in the universe.

To welch. To go back on your word. A highly derogatory word made popular through the be-mag messageboard crew in response to wirolla's act of cowardice.
Wirolla had two options; tits or GTFO. He welched, he chose the second option.
