A Boulianne is a French math teacher that poses sexualy at random times. A big turnoff towards girls. His breath might have a stench of mothballs and crap.
Nicknamed "Gros minoux" which in english means Big kitty.
Some sort of white saliva might be in his mouth.
"Who did you have for last period?"
"Yeah, his breath really stinks, and he stares at me."
