scored the sinslide

This can have two meanings. One is simply and FINALLY getting to having sex with someone you have wanted to for some time after overcoming many obstacles. The other meaning is rating the act of the sinslide afterwards.

Willie: I finally got to scoring the sinslide with Rach!
Bronk: Well, from the sounds of it you are stoked to have finally scored the sinslide, but seems like you would have scored the sinslide with a positive rating!
