similaic onomatopadjective

A part of speech that combines a simile(comparison using "like" or "as"), a onomatopoeia(word that imitates a sound), and an adjective(describes a noun). Relates a quality of something while denoting a sound associated with that thing.

"Wow, did you see that silver Corvette, it was like VROOM!" (VROOM would be the similaic onomatopadjective in this case)
