a person who continuously insists that they have keen insight into every discussion known possible. however, no matter what they insist, this is untrue.
some kid: like, omg, i failed my test today!
some other kid: oo that sucks you should have studied more
velroth: well if you ask me the test was written very poorly by the teacher, but if you wanted an advantage to this test you could have done this or that or studied while listenign to music.. experts say that the best way to study is in short increments of time and drink lots of fluids... although it doesnt really matter what you got since it will stay the same and youre stupid, while i, of course, am not. this is because i know more than you about everything.
