The Big Nasty

The actual act of sexual intercourse, man-to-woman; woman-to-man. When I was young (many eons ago) they had the 'base' system:

1st base: kissing and maybe some 'under the sweater' action
2nd base: french kissing and fondling
3rd base: naked bodies rubbing together, but NO penetration
4th base or home run: sexual intercourse

It got stupid to say 4th base and saying home run during baseball season could be confusing. So the act bacame The Big Nasty.

Susie: Did Johnnie feel you up last night, Nancy?
Nancy: No Suze, we went all the way. Enjoyed The Big Nasty, donchaknow.

Big Nasty

Any large person who refuses to engage in daily personal hygiene, often smelling of rancid garbage and/or rotten cheeseburgers with onions on a hot day. Also the same person who refuses to courtesy flush who may have had a gastro sleeve whose stool is unbearable to the point of choking and/or vomiting.

Oh oh, get the spray out....here comes Big Nasty!
