Narrative:
We were cleared for takeoff 34R. Another aircraft had just cleared runway 34R at east and not turned south on to B taxiway. We were cleared for takeoff. As we approached east on 34R we were in the process of rotating and it was apparent that the other aircraft's tail was not on the taxiway side of the intersection markings. The tail of the other aircraft was not intruding over the runway side marker paint. As we passed the tail of the other aircraft we experienced a strong bump from his engines. Takeoff and climb were normal after that.
