"There is a flush draw" to the same tone as "there is a flag" when someone scores a 60 yard TD and it's about to be brought back.
"There is a flush draw" is something you feel on a 2-suit flop with 5 players. It implies that you a) will not be able to slow-play your hand against crushed ranges without giving away a free card b) you're not in great shape as opposed to a dry board, c) you're gonna have to take the variance against floats and semi-bluffs, and a whole bunch of other stuff.
I just had that happen to me with QQ. Raise to $20, 4 callers.
Flop (~$100): AQT two spades.
Check, I check, guy bets $20, folds around. I raise and he folds.
fold, fold, CO raises to $0.75, fold, SB calls $0.65, Hero calls $0.50
Flop:($2.25, 3 players) 4 Q 6
SB checks, Hero checks, CO bets $0.75, SB raises to $1.50, Hero calls $1.50, CO raises to $4.00, SB raises to $9.25, Hero raises to $24.25 and is all-in,
