"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.
