Top definition
A term related to quantities of marijuana smoked. May apply for college students and maybe high schoolers. Refers to the number of bowls smoked compared to the number of classes (all scheduled or only those attended). If this ratio is above 1 for somebody, then that person is probably a huge stoner.
"I smoked 6 bowls today and went to 3 classes (had 4 but skipped 1 'cause I'm a stoner). That means my Bowl-to-Class Ratio is 2."
