In poker, when you hold a strong starting
hand and raise a lot of money to see the flop, only to have not matched any cards when seeing the flop making your
hand completely
useless.
Starting
hand of A/
K. You raise double the blinds, someone else raises double that, you raise again or
go all in because you're pot committed.
The dealer turns over the first three cards (flop) and it's 5/2/J all of suits other than the ones in your
hand. Probably giving the other guy a really strong
hand against you and effectively costing you all your money.
That, my friends, is getting flop nobbed (a Flop Nob).
Common usage: "Hey man, the tables were rough last night, I was constantly getting Flop Nobbed!"
