To add to bigbadron...
It's been proven in multiple studies and research that people who heavily drink before the legal age of 21 can suffer immense brain damage to the parts of their brain that hasn't developed yet, which is WHY the drinking age is 21.
The human brain never grows or expands, it's typically a regular size and only expands as you grow older and stops growing around 21 years of age. Different parts of the brain "activate" at different times, and if a teenager drinks his/her ass off all the time, they are damaging PERMANENTLY undeveloped parts of their brain as well as some developed parts, essentially making you a fucking retard.
My cousin drank a lot with her friends from 13 to 16 and a recent cat scan showed her brain activity to be about 60% of a normal person her age.
If you're a teenager, you shouldn't be drinking. If you do, then whatever. Live in the moment and fuck yourself over. No one would care anyway if your that stupid already to kill yourself with alcohol.
As far as the girlfriend, she's a fucking loser. I hope she has the worst hangover of her life.
Oh lookie me, I'm drinking underage with my friends!
