To fly completely off the handle, in a fit of rage at 1000mph.

Dave caught his Mrs in bed with his mate, he went scalextric.

scaletrix 

Refers to the sexual act of tying a woman to the ground and inserting a scaletrix track up her anus until it comes out of her mouth. This is then joined back on to the other end to create a circut. Much fun is then enjoyed using her as a tunnel.

I scaletrixed your mum.
