PS $50 - I hate this spot so much

[Mackerel]

CO has been sitting out several rounds, and will be all-in in the BB next hand. SB has been abusing the bubble, pushing at least 4 out of 5 hands for a while now. Button and I have just been meekly folding, waiting for CO to blind out. Then this hand comes up.
