"Yuck! What was that, belly button lint?"
Harry Potter's reaction upon eating a belly button lint flavoured Bertie Bott's Every Flavour Beans.[src]

Belly button lint is an accumulation of fluffy clothing fibres and, to a lesser extent, dead skin cells in the navel cavity.

Belly button lint is a flavour of Bertie Bott's Every Flavour Beans.[1] Harry Potter personally found this flavour revolting.[1] Navel Fluff Buster is a wizarding product designed to clean lint from the belly button.[2]
