A bumbleberry is a mixture of a burble berry and binkle berry from the giggle bush.

Bumblebird 

A) A mysterious cryptid that resembles both a bumble bee and a hummingbird

B) When you're a fucking idiot and can't remember the word for hummingbird.

I blanked on what a hummingbird was called for a hot minute and I kept trying to force bumblebird to work as a word like a little kid trying to force a square block through a triangle hole
