When a person tries too hard to be right. When someone is MARVINING they force life and trying to be right about something.

Marvin is a generally sweet guy, falls in love easily. He's soooooo funny, he can be cocky.
That guy doesn't always make the smartest decisions, though.
He has a great body physique, amazing talent at making out, most likely tall.
He has a nice cock. =
Marvin is one of those guys you'll never , ever forget. He's an amazing friend, boyfriend...just a great companion of the opposite sex.
girl 1 wow, he's perfect...with some glitches...and he's not GAY!

girl 2 He's gotta be a Marvin!

Marvinism is a religion founded as of the late 2017 era. Followers of Marvinism are called Marvinists, and belong in The Holy Marvinity. Marvinists follow their God, Marvin. He is, surprisingly, a fish. This usually throws people off, but a philosophy of Marvinists is to never judge a book by it’s cover. Moving forward, Marvin is a tall, pale and warm yellow fish with dark fuchsia or purple stripes in his fins. He also has off-white eyes with black pupils.
