1) A small, liberal arts college southwest of Philadelphia, founded in 1864 by the Religious Society of Friends but no longer affiliated with them officially. Swarthmore College is known for its rigorous academic program, which has prompted its students to adopt the unofficial motto "Anywhere else it would have been an A." Swarthmore students do have fun in addition to their schoolwork, but when asked, they find it easier to complain that they don't.

Puna butter is a colloquialism used by native Hawaiian's to reference cannabis. Though generally "a high quality marijuana bud", as described above, the origination of the term, to my knowledge, is specific to the Hawaiian Islands. In the definition and context listed on this web site, "Puna Butter" would have the same meaning as "KGB" or "Chronic"; a superlative or extremely potent variant of marijuana, when in fact "Puna butter" is more in line with more "common" terms like "weed", "grass", "pot" and "reefer", a regional reference for marijuana w/o regards to its potency.
