Girls with awesome ass(ets) showing off their wares at the beach.
Heather: great workout. I feel awesome!
Lori: I know me too!
Heather: wanna go shake some cake by the ocean and catch some rays?
Lori: Bitch you're on!
I would like to protest your denial of "Cake by the Ocean" that I submitted. It does mean to toss salad, or eat booty. If you listen to the official video on youtube you can hear the band singing " I keep on hoping to eat (booty) cake by the ocean." When they say "booty" is is in a lower voice, you have to listen for it.
Also the girl it was written for called her backdoor "Cake"
