1. Something that is punishable only in the U.S.

2. Something that 18, 19, and 20 year olds can be charged with in the U.S. due to their fascist drinking laws.

3. Something they don't allow 18, 19, and 20 year old American soldiers to do before they come home from Iraq in pieces with only an American flag handed to their family for comfort.

Get the Underage Drinking mug.
An activity commonly engaged in by people who are too young to legally drink, too unimaginative to do anything interesting or healthy, and too afraid of being found out as bores to interact with other people when they're sober.

Unfortunately, most underage drinkers remain dull and uncomfortable with themselves after they turn into regular drinkers who don't need to use fake IDs to sneak cheap beer and liquor.
I wanted my roommate to meet you guys, so I invited him to come with us on this hike. When he found out that we weren't bringing any alcohol, and that we were just going to take some sandwiches and try out my new camera, he decided he'd rather sit on his ass in his room getting drunk and watching cartoons on DVD.

It's too bad, because he's been complaining about how fat he's getting, and we must've burned about 1000 calories today. He always says he's bored, but every time somebody invites him to do anything other than drink he turns them down and says whatever they're doing is stupid. It's like he thinks that if underage drinking isn't involved, it can't be interesting. I think he would have liked seeing those bald eagles trying to catch fish and those hot girls we passed by the bridge. He played basketball in high school; maybe that game we're planning for next week won't be too "boring" for him.

Hopefully by the time I get home he'll be too drunk to yell at the television, but not so drunk that he's puking or blacked out. Had to call an ambulance for him last month when he blacked out; that was lame. I'm also tired of hearing him bitch about having trouble getting up for his classes - if he didn't stay up drinking most nights he wouldn't have such a problem.

But really - he's a cool guy when he's sober.

The only thing that makes adolencense worth while.
If you don't drink underage at some point in your life, you are considered uncool.

The only thing worth in life is parties and a lot of underage drinking

When a person can fight in wars in risk of getting shot, blown up, hanged, stabbed, and even kidnapped, but is not allowed to drink a simple beverage
cop: you’re under arrest for underage drinking
18 year old soldier: I’ve witnessed my closest brothers in arms dying in my arms. I’ve seen women and children get shot and killed over some fucking tyrannical god. I’ve had to go to the hospital multiple times due to being shot and have even been stabbed once. And you’re telling me that I can’t enjoy 1 beer afterwards.
cop: uhhhhhhh... yes
