n: Arboris Masturbatum:

Small trees that usually accompany unbearably legit things. Are self watering, and some species tend to reproduce at exponential rates. Make sure you have room for them before you purchase anything that may contain large amounts of masturba tree seeds.
Dude, I just got Bioshock, and it came free with fifty masturba trees. I guess I have to go plant them now...

Dude, have you heard about the new Future Trance cd? I'm sure it comes with even more masturba trees than the last one did...

I'm gonna get the 2008 M3, but I'm a little worried because I'm running out of room in my backyard to plant all these masturba trees after beating Bioshock...
