When a young lady or man ( to be inclusive) has had such a fulfilled sexual time that they are literally drenched in man custard.
Doris had choked down as much of Berts man custard as possible but couldn't take it all. Now she we just a spunky mess.

Pete had shagged her so much that by the end of the night he left her looking like a spunky mess.
