look up any word, like smh:
 
1.
A nice way to describe someone who only speaks one language.

Proven Mathematically:
semi=1/2
Bi=2
lingual is the variable
semibilingual=(1/2)(2)lingual
the 2 and the 1/2 cancel out
Bill: Jason, Are you bilingual?
Jason: I'm semibilingual...
3 minutes later...
Bill: wait so you only speak english?
Jason: ... yes
