Part 'oblivious' and part 'idiot', an "oblidiot" is a term first coined to describe idiot drivers who are also completely oblivious to others who may be driving near them in traffic. More recently, the term has adopted a more generic definition to describe those who are simply "oblivious idiots".
Hey, look at this oblidiot! She just swerved across two lanes without looking and cut right in front of me to get in this lane. There were signs for the past 2 miles warning that there was a toll coming up! And here we sit, while she sorts through her purse looking for change. Oh wait! Now she's opened the car door to look on the pavement for some change! Ah! I can't believe it...now she's popped the trunk open! In the tollway booth! Unbelievable!!
when you feel as if you're obligated to go out on a date with someone. I.E: a blind date, an old boy/girlfriend or just someone who has the funds to feed you for one night.
"Sorry Julie, I woud love to go out with you Friday night but the ex keeps calling and wanting to hang out with me, I have an oblidate."
"Josh isn't that cute or funny but I sure am hungry. I guess an oblidate is in order."
