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."
