The first and last minute of this energizing cover of Florida Georgia Line's 'Cruise' are the best parts of the overall hilarious fan music video. These girls don't seem to know all the words to the song, but that doesn't keep them from headbanging and thrashing around the backseat like seasoned rockstars. With dark brown hair whipping around wildly, we're just glad no one bumped heads. 

Near the end, we realize that "Big Lance" was also a part of the fun from up in the front seat -- and his air-drumming skills are award-worthy. Even when he's busted on camera, he shakes off the embarrassment and keeps making time on imaginary skins. We can't help but wonder what people driving by this car were thinking, but we applaud the group for not caring.
