Semi affectionate term used to describe a female who chooses a career path in one of the manual labor type trades historically & currently dominated by males. Like auto mechanics, welders, carpenters, truck drivers, Sheet metal fabrication, and the like. To identify a Nasty Gash (or in mixed company "NG") such women dress and act much like their male counterparts. This term does not in any way mean that the female is autiomatically a lesbian, or decidely unattractive in any way. Many "NG's" would actually clean up rather nicely if they ever bothered to, or owned any clothing that was even remotely feminine. It also carries no negative connotation as to their abilities in said trades. Additional verbage would be used to describe such.
"We got a new "Nasty Gash" starting at the shop. We'll have to see if she's any good or just a token hire"

If a man knows for sure he is going to be getting lucky on some big occasion (Valentines, Birthday, etc..) that day (or a couple days before) he eats nothing but nasty substances and things that plain and flat out do not taste good alone without any aditives (Onions, Horse Radish, Aspargas, etc..) after that you wait until after the dinner and stuff until it is time to get head or have sex (if you have sex you must make sure u pull out or it will not be as fun) and when it is time to cum you make sure you drain it all into the persons mouth (also make sure you watch their face) odds are that the person will not be pleased with the new taste of that your cum has suddenly developed...always fun for a guy who likes to joke around
