Columbian Birthday Cake

Putting a bunch of Columbian Bam Bam on your dick right before you bang a girl in the ass. Then blow your load in her ear and slap the side of her head.

I was over at Donna’s last night and gave her a Columbian Birthday Cake! Happy birthday to me!

big ol’ birthday fart

The result of a person whose birthday it is eating everything under the Sun that will improve their chance of blowing a huge, incalculable volume of flatulence onto their heavily candled cake in order to quell all the candles with a single, window-rattling flutterblast.

Yup, as we all stood together ‘round the cake, we were suddenly blown right off our feet by Grandpa’s big ol’ birthday fart; he’d been workin’ on that thing for days.
