a person (often a pre-teen male) who farts in a bathtub so that they might bite the bubble it produces.
John, a legendary wiffer sniffer, leaned back in the bathtub with well-practiced ease and farted, then just as quickly, leaned forward again and bit the bubble.

A young person.
A word that I believe that older people use.
Aww look at those cute 10 year olds reminds me of when I was a young wiffer sniffer!
