A person (preferably of the male stature) who somehow persuades you to lay slightly on them, but then goes forth to pin you to them; a situation where you are unable to get out of a creepy guys grip.
However, usually this person is not someone to fear - rather, someone who doesn't give you the proper breathing room when you find it necessary.
