Someone who goes around slapping the living bajeezus out of dillies.
Dear Otis,
A dillyslapper is someone who does a d1lly of a job in slapping together bad meals on short notice...for example, a dillyslapper might be a short order cook in a greasy spoon.
Lol :) I can't really say what I first thought when I saw the word "dillyslapper" :p ummmmmm this song can say it for me then :p
Hard to put in words here but it's like this.
That sounds like some sort of sexual innuendo.
In British slang a slapper is a woman who puts it about too freely. And since a dill is somebody who isn't very bright, a dillyslapper would be an indiscriminate woman who fails to take precautions.
Someone who has been commissioned to slap the di1y off your face.
Well, I'm going with a particularly guffaw-worthy story or joke .... A combination of a real "d1lly" and a "knee slapper". (I had to use that "1" in "d1lly" because it kept telling me to check my answer for foul language!)
