Welch

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.

welch

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.

Welch

Dumb ass bitch who never does what they say they're going to do.

There's a welch on the phone who said she'll be here at three, but we all know she's not going to show up today.

welched

Treated someone like the Welsh have been throughout history, that is ripped off. So the winner of a bet may recieve a welsh prize - nothing. From the outdated adjective welsh - meaning disadvantaged(in poverty and fate).

TheTruth : Yeah Dave did win the bet but I think he may be Welsh so it doesnt count.
Dave : I've been welched
