Black Jack Scale 

An alternative scale of judging female attractiveness that is similar to black jack. The lower the number you give the female, the more times that you would like to have intercourse with or "hit" the female. Inversely, higher numbers are reserved for females that are rather unattractive and in most situations in which you are not piss drunk, you would not want to have intercourse with or "hit" the female.

Damn that girl is fine! She's definitely a 1 on the Black Jack Scale. I'd hit her again and again and again!
Holy shit that girl is nasty! I'd never do her, she's a 21 on the Black Jack Scale no doubt

The Jack-o-lantern 

The process of shoving a flashlight, the brighter the better, into a female's vagina. Once the flashlight is inserted correctly the flashlight is tunred on. This will create a Jack-o-lantern effect. This can also be done with a strobe light for a different effect.

My girlfriend and I were so drunk and horny after the halloween party, so I decided to give her the Jack-o-lantern
