look up any word, like eiffel tower:
 
2.
portable device for transporting and storing an entire porn collection
7 or more just like with stiff cock length the porn drive needs to be 7 or more gigs to hold one matroska compressed HD dvd porn disc

the more surface area the better for hard drive porn drive storage and boners. The more stiff boner surface area the more nerves for orgasm either naked at the computer or balls deep into a girl preferably her contraceptive ass.

1.
TrueCrypt encrypted device for safely storing pornagized porn to avoid getting caught by parents when not orgasming or a safety net when boxers are around feet when orgasming

TrueCrypt encrypted device easily carried in jerking shorts to share porn or watch with friends
It doesn't matter if the drive can be concealed from parents as only you can decrypt the porn drive to use it: TrueCrypt allows for a false exterior container to "show" there's no porn in it, and an interior container with different password for the porn you and your friends will use for your daily seven and better couch jerk.

The more guys who bring a porn drive to the sleep over the better. No porn hogs invited.
