Not to mention on the same thread mixing political talk with talk about slang like this:

The word "dis-associate" made me think of all those [mostly Republican]politicians who are now trying to get as far away from Abramoff as they can. These fat cats are dissin Abramoff big time.

"dis"-to insult or thwart in a social manner, short for disrespect.
