Crispillingus 

The act of ripping open a bag of crisps and licking out the salt and potato fragments in the corners.

Glowering, Reginald ripped open the near empty bag of salt-and-vinegar and performed an act of ecstatic crispillingus on it.

Licking out the crumbs and flavour from a crisp packet

I love performing crispylingus on a packet of walkers prawn cocktail.
