A mantacorn is a strange hybrid between a Manta Ray and a Unicorn. This animal only exists in strange LSD-induced dreams, and in the minds of young children!
Magical creature that has one horn much like a unicorn but is much more magical, the horn is covered in cocaine and as a result of this the creature runs around very happily saying yayayayayayayayayay all day everyday.
A mythical creature with a lion's body, a man's face, a scorpion's tail, a bat's wings, and lots of rows of really sharp teeth. These guys usually don't get along with dragons. Personally, I'd side with the dragon if a manticore and a dragon got into a row, cause I way like dragons better. Oh yeah, manticores are usually orangey-colors.
For one man to force another man to do anything through male peer pressure in that special trademark way.
This includes verbally degrading their ability to do anything or stressing a scoff full of testosterone and disbelief to make the person feel inept.
Usually ends up including "do you want me to do it FOR you?", and typically ending up with the situation in question turning out poorly even though the person in question succumbed to the mantagonizing.
AJ: I don't think I'm going to fit into this parking spot...
Brett: Oh come on, you've got plenty of room.
*AJ starts backing the van up*
Brett: Are you serious right now? Do you want me to park the van for you?
AJ: Fine, I'll park here.
*AJ parks successfully*
Brett: Now we've barely got any room to get out. Whatever...
Dev: That was funny.
Andy: Chyep. Is mantagonize a word? If not, I just coined that because that just happened.
a mythical male creature who is successful (read: pursuing his passion and can pay his electric bills/rent), funny, chivalrous, masculine (read: not chauvinistic), adventurous, artistic (read: not suicidal).
See any John Cusack film (or Chuck Klosterman's witty commentary on Fake Love in Sex, Drugs and Cocoa Pops), any romantic comedy where the flawed guy comes through in the end...
"Where is my manicorn? I keep going out with all these losers!"
"Too bad I settled when I got married, I just met my manicorn."
