Ronda Rousey -- Marine In 'Complete Shock' ... After Video Date Invite Goes Viral

The U.S. Marine who invited Ronda Rousey to his Marine Corps Ball says he's in "complete shock" after his video got nearly 4 MILLION views online ... and says he's still hopeful she'll say "Yes."

The Marine with the massive cojones is Jarrod Haschert -- who joined the guys on "TMZ Hollywood Sports" to update us on his plan to make Ronda his date for the December 11th event.

The bad news: he hasn't heard back from Ronda yet.

The good news: he's still super confident and even has a game plan in case she takes him up on the offer.
