The phrase "Osh Posh!" is an insult of sorts. It is yelled at the end of sex, if the sex was bad. It tells the partner that they are boring or uncomfortable in bed, and they should really work on it. It is not only a one worded phrase used at the end of sex, but can also be used as an adjective.
"John Doe is very osh posh."

The act of attempting to fingerblast a member of the female gender, and being denied due to prudence. In an act of desperation and pride as he would not be denied his fun, the male member proceeds to attempt to pleasure the female through the pair of jeans that she is wearing. Possible side effects include: abnormally large blisters on the fingers used that resemble tumors, elbowing your friend, extreme perspiration, and shame.
Marc gave Christina the now infamous Osh Kosh B'Gosh in Chris' basement, while under a blanket, as everyone was attempting to watch a movie. This resulted in Mike being repeatedly elbowed by Marc, which led to Mike exposing the Osh Kosh B'Gosh in progress. The next day, Marc was spotted with an incredibly large growth on his right pointer finger, with turned out to be a blister.
