"Lookin #hella naked at a late night dinner with my @monsterenergy beezies. Referenced the Bay area with my #Hella hash tag specially for @summerdaniels21 ! @cassidygray @brett_foskett @ammichaelsen #SideBoob," Terrell wrote.
"Hella" is a slang phrase often used on the west coast of the United States, and Terrell apparently enjoyed it so much that she incorporated it into her Instagram photo hash tag.
Most companies spend their money on ad agencies, TV commercials, radio spots, and billboards to tell you how good their products are.
Instead, Monster Energy supports the scene, bands, athletes and fans with a gorgeous roster of "Monster Girls" that help promote their brand.
When Terrell isn't spending time as a Monster Girl, she can be seen ringside at Bellator Fighting Championships MMA events around the country.
"It's probably not the life for everyone but I love it," Terrell said of her hectic travel schedule. "I believe that life is what you make it. I live my life to the fullest and I do my best to make sure that I don't take anyone or anything for granted."
