Anyone can file a complaint about anything. You are now moving the discussion in a different direction.
Perhaps I should have continued: depending on the college, the Dean of Students might then subject you to a Kafkaesque trial, in which the identity of the complainant (the slut who threw herself at you while drunk) is kept secret, in which you are considered a rapist simply because of the complaint, and in the end will be expelled from the college, regardless of what defense you mount.
If you doubt me, read this piece, from Slate of all places.
