BUMP N GRIND 

Bump and grind referred to the seductive walk of burlesque performers, which contained a lot of hip action. As the hips moved in one direction they were said to grind, stopping with a bump; then grinding in the other direction and repeating the pattern, back and forth, back and forth.
this is an old fashioned definition

Look at her walk. She can really give them the old bump and grind.

axe to grind 

To have a grievance with someone, especially where one feels the need to seek damaging retribution.

The phrase probably originates from the act of sharpening an axe with a grinding wheel, with the intent (in this definition) to get revenge on someone by maiming or killing them. ;)
