Get the Backdoor Gyromug. 
An ugly, nasty, gross ass potato chip created by Lays© and it tastes like your grandma chewed up a dirty burrito found in the garbage and it was feed to your baby cousin and he threw it up and someone made it a chip and gave it to you!

Get the Georgia Gyromug. When one guy is throat-fucking a woman and one guy is ripping her asshole with his penis while she is vomiting and having wet diarrea at the same time.
Last night Steve and Frank gave me a greek gyro, i was vomiting and shitting on both of their cocks it was magical.
