Ruined orgasm

Lately I've been seeing titles of porn vids that say something about a 'ruined orgasm' and I can't figure out what they hell that's supposed to mean. Can someone shed some light? At first I thought maybe they were talking about premature ejaculation but that doesn't seem to be a tie in to this 'ruined orgasm' stuff.

I think that's when they stop fully stimulating the person either right before orgasm or in the middle of orgasm so the sensation isn't as strong. It's a domination sort of thing.

thats when you doing bdsm its a control thing for the dom
