Yes, Trill is a brand of bird seed. To some.
To others the descriptive term; Trill box is an adaption of the term seedy. A word used to describe an occurance or a person who has acted in an 'alternative' fashion. eg. macking younger hoes, drinking foreign vomit, inserting pens in the anus, pissing while man-gina-ing, pooing on front lawns, wiping poo with a bare hand... you get it, all worthy of the title 'Trill box'.
