The act wherein a man is about to ejaculate but chooses to hold back his load while holding his breath until the point of explosion. This results in the first squirt of semen taking the form of a puffed mushroom cloud. The puffed effect stems from the redirection of air due to the breath being held in addition to the eventual oral exhalation. The puff can also be emitted from the phallus in the shape of a freshly spun wisp of cotton candy and tastes just the same.
My girl was giving me a blowjob and I held back until I couldn't hold anymore and I blinded her with a kreme-puff.
