Jethro

Noun. See also "Awesome". A person that exemplifies awesomeness. A man with an angellic face and the body of a god. Just saying the name will cause all womens panties to drop withing a 60 mile radius. Too much use of the name may cause health issues such as nosebleeds, myopoism, hangnail, the gout, shingles and anal and vaginal leakage.

That guy is so Jethro.

My vaginal leakage was caused by Jethro.

Yeah, he definitely pulled a Jethro Marx.
