I had a hand today where I had KK with a very short stack of $2.50 at a NL25 table. I had just lost a big pot the hand before and didn't have time to rebuy. Anyways, after somebody in EP raised it and five people called, I raised all in for 1.50 more and everybody called! The flop was nothing and some guy bet big with a flush draw and folded everybody which was good for me and I ended up taking the pot of ~$16.

I believe that is called "sexing up" in the poker vernacular.

As for the opener in this thread, never fold KK in a position like that. IMO.
