Today after Programming Languages class we established that we (tech geeks) are really a bunch of horny perverts :P Only in our field, phrases like these below are considered normal and appropriate:
A floppy is good but a hard drive is better. You may also sometimes need a USB dongle.
Your web-app should have a nice front end and a solid back end. You should also avoid being rooted.
When you log into a unix machine you can finger your friends. You can also get head, and get tail (of a file), take a dump, or mount something (a drive). You may also fsck your drive :P
And apparently on a vax machine you sometimes need to anal (analyze) the drive (thanks Brian).
