so stink

[RonButters at AOL.COM]

Here is a great website that has yet another truncated form comparable to
"whack" and the rest:

http://www.iol.ie/~pbalfe/newpage18.htm

See:

Yo mama so stink, she has to creep up on bathwater.
Yo mama so stink, she sweats Black Flag.

Note, however, that we get

...   so bald, you can see what's on her mind.
...   so bald, she looks like an overgrown testicle.

and

so slutty, her legs are like a 7-11, open 24 hours a day.
etc.
