Horror movie cliche, someone's bus?

Theres a phrase that describes the thing in horror movies where they kill off the music, make nothing very interesting happen on screen and then make something shocking happen like something jump out and shock you...I cant remember it though. Like in most modern horror films...its cheap and very lame.

Its someone's bus...after a film where a woman thinks shes being chased down the street and it gets incredibly tense...then a bss pulls up and scares you. Its the directors name I think...
