I stay away from those types of hands personally, but when you are in BB or SB and see the flop for practically free, they can be speculative hands.
Live tourney today. 4 callers of the BB, I was in SB and completed the blind, 2000 chips for the cost of 200, worth looking it up. I flopped top pair and a flush draw was out there. I bet 1.5BB to look weak and test the waters. 2 callers. Turn came King, giving me trips (with a jack kicker). Flush draw was still out there and I did not want to give the one guy i put on a flush draw a chance. I was already somewhat short stacked and after putting in my BB and my 1.5BB bet, had 4BB's left, and pushed in. One insta call, one fold, and Im staring at KQ across the table from my KJ, and nothing on the board to save me.
I call this "shit happens", you get priced into completing a blind, hit top pair, test the waters, turn trips, only way id get out of this hand was if I had enough chips that I could have folded if the guy re-raised my 4BB bet (which was all in)
