The NY Observer reports,

Visitors trolling for casual sex on Craigslist.org last week were left scratching their heads over an unfamiliar reference that has surfaced in a flurry of recent postings.

“I keep seeing this term ‘Frum.’ Can somebody please clue me into what the hell that is?” wrote Jeff, a 30-year-old regular on the site.

Geez, why can’t people just use Frumster for their casual sex hookups like everyone else does? (c/o Protocols)
