A "Leeroy" or more specifically a "Leeroy Le Gallais" is an insult meaning "someone who has sex with horses". It also is used to refer to someone who is a bit rurally simple, or generally used for "idiot".
The terms "a Leeroy", "doing a Leeroy" and "to be a bit of a Leeroy" etc, are easily confused with Leeroy Jenkins
(who became infamous from World Of Warcraft
for leaping headfirst into a situation regardless of strategy), hense the use of the full term "Leeroy Le Gallais". Usually the short version "a Leeroy" is used when context will suffice to explain.
The insult was born after public outcry in Guernsey
when a Guernseyman hit national headlines when he was taken to court for molesting a horse (locals couldn't believe that some freak would actually do this, Guerns
aren't all like him!)
"I think he's a bit of a "Leeroy Le Gallais" if you know what I mean."
"What are you, some kind of Leeroy?"
"He looks futu
! I reckon he spent all last night Leeroy Le Gallaising"
"That mare looks like its been Leeroy Le Gallaised"
"You've got to remember - they're a bunch of Leeroy Le Gallaises!"
