Here is an airline ad spoof making fun of the print advertisement behind its back, so to speak. You can see the two ads back-to-back below.
I hope this airline ad spoof will not get these Malaysian girls’ back up when they see this silly spoof. I know these curvaceous Malaysian girls with beautiful rump, wish I get off their back and stop making fun behind their back, or rather at their backsides.
Anyway, here are more words for backsides:
buttocks, ass, arse, behind, buns, derriere, fanny, hind end, hindquarters, keister, nates, posterior, prat, rear end, tooshie, tush, seat, fundament, backside, bottom, stern, rump, tail end, tail, rear, bum, butt, can, gluteus maximus, haunches.
