The Dementor is a sex position where you assume the misonary position. You then place the blankets over your head like a Dementor from Harry Potter and push down on her stomach, taking all her breath away. It is at this moment you must climax and then make the high pitch squeel of a Dementor. If said female then yells "expecto patronum" well, then you marry her.
She said she like Harry Potter and I gave her The Dementor in bed last night.

The most Ballin Drink you can make, Brass Monkey a 40 of Old English with Purple Drink, called the Dementor because it resembles "Dementor Piss" according to Jonny Haworth. WARNING: you will feel like you just got the kiss of death from a Dementor if you can conquer this beast.

this is when you are making out with your significant other and you casually put your hands on their cheeks, but then quickly plug their nose and try to suck the air out of their lungs.
