an individual (typically a male) that spends much of his freetime during adolescence watching pornography in the privacy of his basement/darkened bedroom/at a friend's house while simultaneously consuming -ito dust-covered chips (usually Nacho Cheesier Doritos). A D.E. (Dorito Eater) is marked by his inability to "get some" in the real world. Even though most individuals exit their D.E. phase by the age of 15, a former D.E. is easily identifiable by his didgy-dodgy behaviors involving women.
"It was so weird...when he asked me to suck his fingers while we were hooking up, I could almost taste the Doritos on his fingers from seven years ago. He's such a Dorito Eater"
