LOL BRIEFCASE is just a random thing that people yell because it's funny.

The origin is not certain, but the furthest I've been able to trace it is to a person named PsychicMaster on Warcraft III (Azeroth). He came into the Clan GS channel randomly and just yelled it. Then he'd leave.
PsychicMaster has joined the channel Clan GS.
PsychicMaster: LOL BRIEFCASE

A mini lol is a laugh that is not quite 'lol', but is still technically a 'laugh out loud'. It is in between ':|' and 'lol' on the lolage spectrum. It's a quiet laugh, the real-life equivalent of 'Heh'.
Person 1: Your mum is fat.
Person 2: Well you're gay.
Person 1: Man, I was just joking with you!
Person 2: ...mini lol?

An Auto-LOL is when someone on IM will respond instantly with "LOL" even with what your saying isn't funny at all. Just to continue on the conversation.
Zarbula: So, I ate tacos for dinner tonight
