Tip Drills?

What exactly is a tip drill you ask? Oh...my friends, do you have something to learn.

Apparently Nelly (the rapper) had a song called Tip Drill, and since I had never heard about it until today, I decided to hit myself w/some knowledge. I went on youtube and watched the video (it's so risk-ay you have to log-in to see it *gasp*). Well...it was pret-tee vulgar...obviously aside from porn - such as Cup Chicks. It's a wonder how girls even get respected at all anymore when you have women degrading themselves in this fashion. I feel like I can't even blame men, b/c at some point, a woman's gotta have self R-E-S-P-E-C-T. Neway...

After watching the video, the question remained unanswered...what is a tip drill?! So...I inquired about it via internet and found some interesting explanations...all of which left me w/no solid answer, but a better idea none the less. Here are some of my favorite answers on this one website:

"a tip drill is not a ho or an average chickenhead. a tip drill is like a butterface. everything looks good but-'er-face. its a chick with a bangin body but an ugly face. I cant stand tip drills. i hate it when i see a girl from behind and she looks like she got a nice body, then she turns around and her face looks like a wildabeast's."

"me and my boy dizzy dave is sippin' on same gatorade, don't call it haterade pimp. lookin for some tip drills aka face like andre with a bangin body. i'm talkin body like an hourglass. if you're in naptown and lookin to party hit us up @ 317-403-2526. holla
ozone and dizzy dave"

...and then there were several posts about ppl saying they knew specific tip drills and called them out by name...but I won't do that on here, cause I'm a lady. For further ehjuh-muh-cation, here are links to the website that helped guide me AND a link to the video. Holla atcha girl.
