hacb
A loud and obnoxious way to greet someone that sounds like a confused toddler having a meltdown in a pizza box. It’s mostly used by people who think they’re cool and can’t handle being ignored.
Pegasus screamed HACB at a guy who tried to steal his loot in PvP
Dread yelled HACB so loud it broke the ventrilo software
A noob asked what HACB meant and got called a baby
