A goobinator is a slang term for a rapist. Sometimes the word goob is used to describe rape, i.e. "He goobed her in the ass", so in turn a goobinator is a person who commits rape.
The goobinator got 10 years in prison for what he did to those girls.

A Goobin is a super goober / hardcore person whose been a goober. It's a pormanteau of been and goober. Together they become a Goobin.

ps. a goobin is not, and never was a literal goo-bin, or a bin for goo. That's just dumb.

Back slang for - been goofing. Especially when the goofing is taken to a serious pro level.
