Yestermester

Last semester. The semester before the current one.

Steve: I wish I did better in English yestermester. I have to take it again this semester.
Dave: You're a fag.

Yesterpoon

The girl you have no feelings for and had sex with the day prior.
She sticks around thinking she's your girl afterwards.

Yeah, man, She's just a piece of Yesterpoon. Don't mind her.

Yestercoff

Yesterday's coffee disguised as a deliciously, freshly brewed cup of coffee.

The instant you take a sip of your freshly-brewed, hot, hazelnut delight; a cold sensation hits your lips and you shriek, "DAMMIT!  CURSE YOU YESTERCOFF!!!"

yentenna

The feeling a matchmaker or yenta gets when she spots a potential match. It's her love radar kicking into action.

"OMG you'd be perfect for Jake! Why didn't I think of that before? My yentenna are working overtime now!"

"Now you've got my yentenna up and twitching. I could totally set you up with Jessica. You're both Giants fans and you like dogs! Yay wedding bells"

yesterbae

Another term for an ex you dated recently or in the near past.

When you see your ex in public and you say to your friends, look that's "yesterbae"!
