look up any word, like rusty trombone:
 
1.
1. to put off or delay

2. to leave things as they are; to not
change or disturb a situation.
1. I paid huge interest on the phone
bill cause I let it slide for too
long.

2. I wouldn't fight over something
that stupid, best just to let it
slide.

3.
if something is awkward or different just keep going to see how it goes
if you are having sex and it starts getting a bit kinky and she slips a finger in your bum, just let it slide and see if you like it
