A very hardcore and conceited person who drinks at least two monsters a day. They are usually douchebags who are extremely athletic and energetic. They view themselves as the coolest most awesome people on the planet. They constantly have energy and usually die at a young age due to the large intake of chemicals. Most monster chuggers are extremly manly and don't shower often. They also have heavily gelled spiky hair and only wear shorts and sweatpants.
" Dude thats your seventh monster, your becoming a monster chugger this needs to stop."
