awktagon 

Someone who is awkward to the point where they ruin everything. No one wants to deal with them so they are usually ignored and not wanted in daily life.

Amanda: Guys! Guess what?!
Kasey: What, Amanda?
Amanda: I GOT INVITED TO A PARTY!
Kasey: Ugh, Amanda, why do you have to be such an awktagon..get away from me.

*Amanda walks away*
