The act of hooking a lover's upper teeth with your tongue so as to ascertain whether they might have dentures at a ridiculously young age. Most commonly a prelude to oral sex.

Dirty dentures is when you are doing doggy style then when your partner isn't suspecting anything, shit a log into your hand and put it in their mouth making a mold of their teeth. Thus giving you dirty dentures.
My girlfriend and I gave dirty dentures a try and it was amazing, the only downside to it was that it left a shitty taste in her mouth.

Getting a blowjob when the the person giving the BJ bites the foreskin of the penis, circumsizing it. the "bj giver" then eats it and poops it into the nostrils of the person recieving the blowjob. they sneeze it into a cup and have their grandma drink it with a cat or dog humping the grandmas leg.
the other day me and my girlfriend decided to try grandma's yellow dentureson... good thing im not jewish!
