Slide Cancel 

“Slice Cancel” in Call of Duty is when you slide and cancel the animation to reset your tactical sprint animation allowing you to move a lot faster around the map if used properly and if well practiced you can have a better advantage over your opponents.

I was slide canceling around the map and got an ACE with my crazy movement.

Slide down the dinosaur 

When a woman wants to have intimate relations with an older man, especially when that man is a cuckolded husband or otherwise less-than-capable partner. Also could be an old, trusty dildo that's well-used.

She was bored with her household chores, so instead chose to slide down the dinosaur.
