A girl (or sometimes a boy, like royo) that has unnaturally big breasts for his/her age.
Usually can be spotted during sportactivities like running. These people have massive hormone-machines inside them.
Dude #1: Hey check out that boobtron!
Dude #2: Wow, she sure is wiggling with the twins Dude #3: Ya she shouldnt be running
-After that everyone is quietly looking at the boobtron-
The projectile vomiting action that occurs as result of too many $3 spirits consumed during the two hour cheap drink period at Greenwood on a Thursday night, or what has happened to Badams on numerous occasions in my backyard after being punished by three, possibly four bottles of strongbow white, or if you are Dirty Dale what happens when you are sculling bourbon straight from the bottle, and than think you are in megadeth while wearing a vest, without a shirt on underneath and play some ridiculous air guitar, than blame your present state of complete inebriation on the bbq you ate earlier after yacking everywhere in my backyard.
"dude I don't remember anything about Thursday night. I think I went to Greenwood but I'm not sure. The only thing I remember is having phat bootrons out of the taxi and the driver trying to start a fight with me!"
"man I just had phat bootrons, so give me another beer"
