smart move or just really rude??

[trojanFan]

assume a TURBO sng on stars, about 5-6 players left, blinds are starting to get high and you're the BIG STACK.

the blinds go up every 5 minutes, and legally you've got about 20-30 seconds to make a choice when it becomes your turn. naturally, as you're the big stack, larger blinds are to your advantage.

here's the question:
do you stall? obviously, you'll irritate the other players, but it does seem strategically smart. you could take 20-30 seconds to decide to fold your 52o and fewer hands will be played before the blinds go up. if you did this a handful of times, then the shorter stacks could really feel the pressure of the blinds more.

is this just really rude or is it a good play?

(think of it like this...in football, the team with the lead near the end of the game is going to use every possible second off the clock before starting the next play. same with hoops, the leading team will use every possible second of the shot clock when possible. is this the same type of situation?)

all input is welcome!
thanks
