Top definition
adj. An augmented form of rad or radical.

Typically used to indicate a condition for which the base form is inadequate, or when rad has already been used to describe a lesser related phenomenon earlier in a particular dialog.

Spoken-word usage is far more common than written-word, and so there is some disagreement about the most acceptable spelling. Bio-rad, biorad and bio rad are generally all understood to mean the same thing.

The term is prevalent mostly along the West Coast of North America, from Southern British Columbia though Southern California.
That party was pretty rad, but swimming all the way home after was just bio-rad, man.
