What can I say, Russian, Arabic, Japanese, Mandarin, Latin and Italian topped off with building site English.

Unfortunately it's been so long since I've needed a good vent that I've now forgotten most of what I've picked up. The one that has bugged me the most because it would have come in handy on a few occaisions was a Mandarin one declaring someone's parentage to be an inbred drooling whore and a Dysenteric monkey.
