Thumb in the plum 

While having Doggystyle sex with your significant other you place your thumb in her asshole. There for placing "The Thumb in the Plum."

Jill was riding my ass all day about the chores I hadn't gotten to yet, so when we had sex later that night I put "The thumb in the plum."

Thumb in the Hose Nozzle 

When you're doing a chick in the ass and she gets diarrhea and it squirts out all over the place. Kind of like when you stick your thumb in the end of a hose nozzle and the water shoots out forcefully.

Rich: "So how was fuckin Lauren last night? I could hear it going down in the living room."

Adam: "Well it was good till I stuck it in her ass. Then i got the old Thumb in the Hose Nozzle action and spent the rest of the night cleaning up your leather couches."

Thumb In 

When a male masturbates with his thumb pointing in so it feels like someone else is doing it.

Thumb in the Can 

A phrase used to describe the finality of a decision made by someone.

Once someone has made a decision and can not back out of it.

Derives from the immature act of sticking one's thumb in a can and attempting to pull it back out.

Jim: Why don't you just leave her?
Ted: I can't mate, I've got my thumb in the can now.

Wish I'd have said no to that promotion...now I've got my thumb in the can.
