Babesoarus
A fake dinosaur made up by losers who think hot girls are dumb enough to believe it. Nerds scream this at girls who don't know better.
Hey babe, you're a Babesoarus! You're not even real!
That's not a real dinosaur, you're just a Babesoarus!
You're a Babesoarus, and you're not even smart enough to know it!
