a person whose favorite time of the day is not 4:20... but 2:09. at 2:09, a "brynda" calmly asks his/her teacher if they can use the restroom. once the "brynda" gets into the restroom and is fully confident that he/she is all alone, they begin to ream his/her own asshole with their own fingers. once this has taken place and the "brynda is totally satisfied, he/she then licks his/her fingers, and heads back to class.
