a dirty date is when you work hard all day to get a certain project done no matter what the weather conditions are are any obstacles in your way you will overcome them
A holiday that is on March 28th every year. During "Spank Me I'm Dirty Day" most people tend to get muddy and wraunchy, and spank each others asses repetitively.
Every 16th August, all these dirty slags do slag things and sleep with half the guys anywhere.
Guy 1: Oh my days that girls a slag look at her!
Guy 2: I think she’s loose man
Man 1: She must be celebrating National Dirty Slag Day then! XD
All: *laughs*
