An utter loser or (more specifically) someone who fails spectacularly at a simple action. A scrumper and can be amusingly described as "someone who aims low yet STILL fails."
In software development environments a scrumper is someone who, through careless and avoidable error, brings everyone else to a halt.
"We were deathmatching and Trevor kept blowing himself up with his own grenades... what a scrumper."
"Scrumper over there just tripped over his own two feet."
"That scrumper Ted deleted everything from source control."
A scrummer can also be called a bum, but a high class bum at that. A scrummer is one who wakes up after 11 oclock on a regulaar basis ( weekends and vacations), one who would rock sweatpants regualrly, otfen times with timberland boots. aka scrumberlands, who don't feel like spending the extra 3 $ on "good beer". A scrummer will usualy never turn down a lip, and will find enjoyment in watching tv for more than 2 hours a day, in their sweaatpants. so here's to you scrummers. god bless
