SMEFNAR 

Spontaneous Male Erection For No Apparent Reasons. Extremely common in High School classrooms where cleavage is abundant.

Sleeping in class is also a horrible time for Smefnars, although they are very common.

I was sitting in Math, and when she leaned over a SMEFNAR hit me...

Smeenard

A worse version of a retard, a kid that isnt mentally handicapped but is close enough and no one likes.

Man Taylor is a smeenard.
