When so called big (football/soccer) teams get beat by small teams like Preston (North End), when everyone knows they should be beating #teamslikePreston
The origins of this term come from Jim Lahey of the Trailer Park Boys, a Canadian television show. Shithawked is a verb meaning you got completely blackout, coma drunk last night and maybe even wound up in the hospital.
"Hey Steve, how was your night out last night?"
"I got absolutely shithawked, how was yours?"
"Hey Steve, how was your night out last night?"
"Don't remember, the shit hawks got me last night!"
