wronskian 

A technique in mathematics used to prove that the solutions of a differential equation are linearly independent. Also a term used by math geeks to inform one another when trying to solve a problem, that compounding one botched attempt after another won't lead to success.

Dude, two wronskians don't make a right.

Wronskian 

A sexual act performed, by a man, while having sexual intercourse with a woman. As the woman rides on top of the man, he reaches around behind her and quickly shoves his entire first directly up her anus. At this point another smaller man walks out from the closet and procedes to defficate on the womans head.

"Dude, last night me and billy totally wronskianed this girl."

wronski feint 

One of two things which happens when you're playing Quidditch:

1. In the middle of intercourse, the male withdraws for a few minutes to perform vigorous oral sex on the female (going down hard and fast...), and then continues intercourse (...and pulling back up).

2. In the middle of any sex act, a female signals to the male that she is ready to catch the snitch (by moaning, saying "here it comes!", et cetera) before she actually is. This tactic is used to end a Quidditch match early, without hurting the other player's feelings. It's intention is to inspire the male to "follow" the girl, looking for his own Snitch, and ending the match under the assumption that the female did too.

Neither of these is to be confused with the Wronski Defensive Feint, a move performed in the Harry Potter books.

1. Viktor Krum performed the Wronski Feint on Hermione during their tryst on the first night of Easter vacation

2. Jack was a good friend of Sarah's, so she performed the Wronski Feint when Jack wasn't getting her off. They remained friends to this day.

wrongskin

a brand new word made up by some Twitter dude who thinks that he "Was born to white parents and have white skin but I identify as being black"

I wanted to stand up for the NAACP chick that was faking being African American, so I made up "wrongskin" because I am a victim of not being a victim.

Wronski Feint 

Prior to the act of fellatio, the pubes of the recpient are doused in chloroform. When fellatio begins, the head is held until the "blower" passes out.

They are then flipped on their back and buttfucked.

"Ron gave me the old wronski feint, and now I can't even sit down!" said Hermione.
