Escort / Call Girl - The top of the food chain, does not walk the streets, pays for their own drugs, well respected on the streets and by drug dealers for being on top of their game.
Crack Whore - A Street walker, will perform any type of sex act for money, supports a pimp or old man, pays for their own drugs, has mild respect from drug dealers for sometimes being able to buy their own crack.
Chickenhead - Bottom of the barrel, street walking gutter slut, usually will do anything for their next hit of crack, crack is more important then money, has absolutely NO respect from anyone!
The above are all different ways of classifying hookers. Its a fact that statistically hookers turn 11-14 tricks per day. No one likes to think they are getting sloppy seconds and I don't expect any escort, streetworker, or crackwhore to ever truthfully admit how many dudes they do in one day. The point really is just wear a condom unless you want to give yourself a death sentence.
Quick question....what was meant by hobby? People actually look at paying for sex as a hobby?
