"DISREGARD THAT, I SUCK COCKS" is a phrase used on sites where usernames aren't protected by passwords, which makes it easy for someone to pass themselves off as a previous poster.
It usually goes like this:
1. Someone will make a serious and sometimes
long post under a
random username.
2. Someone else comes along and uses the same username as the above
person and says "DISREGARD THAT, I SUCK COCKS".
3. Some idiots can't tell which one is which, and the original poster gets angry.
4. Lulz ensue.

Jill: I think abortion should only be legal if the mother's life is in danger.
Jill: DISREGARD THAT, I SUCK COCKS"
Obviously, the first post is someone trying to be serious. Someone else came in and simply entered "
Jill" in the name field and made it look as if Jill enjoys sucking cocks.
