1. Receiving a blowjob, while taking a shit on a crystal toilet.

2. Taking a shit on a girl's face covered with plastic wrap , while receiving a blowjob at the same time.

2. A popular well drink: Tequila, Baileys, Half-&-Half and a chocolate egg served in a glass toilet mug.
Nadine gave good head, while I delivered a steamy, glass-bottomed--blumpkin on her cutesy but defiled, little face.

Get the Glass Bottomed Blumpkin mug.
The fine European art of performing the Glass Bottom Blumpkin includes 2 females, 1 male, and a roll of stick or non-stick saran wrap. The male receives a ravaging blow job from one female, whilst the other female, laying on her backside with her dome piece saran wrapped (stick or non-stick), places her face strategically under the male's external anal sphincter. As the male approaches the ultimate climax, he sprays his doo doo butter on the second females saran wrapped dome piece.
At a social event, Nathan explains to Hari last night's turn of events.
(Hari): Yo man what happened with those two bitches last night? Jill looked all disturbed this morning.
(Nathan): OH YEAH! That bitch and her friend gave me a Glass Bottom Blumpkin last night!
(Hari): NO WAY!
(Nathan): Yeah man, I put saran wrap on Jill's face and she laid down under my asshole, then, Pam gave me an amazing blow job while i shat immaculately on Jill's head.
