A guy that does it with a dirty, ugly or gross girl as he has no better options. taken from the expression "you have to slay a few dragons to get to the princess."
"Well buddy, looks like im going to have to be a dragon slayer tonight."
A man that will pursue and bed a dragon (fat nasty bitch). This man is usually of average or skinny size, this term does no usually apply to a fat guy with a dragon. The pair should be somewhat disproportional for it to be a legit dragon slaying
man, my cousin is a dragon slayer....look at the beast that just walked out of his room.
1- A knight's long quest and battle looking for his princess.
2- Hooking up with ugly chicks while trying to find the "princess" (a very painful and long process)
3- "You have to slay alot of dragons before you get to the princess"
Dirk- Hey bro, how was the search for the princess this weekend?
Brian- yeah, I was killing dragons all weekend long , not a princess in sight.
Dirk- Well man, you are the best dragon slayer I know.
