Bookended 

When, while sitting at a bar, a person is flanked on either side by individuals who have chosen to take out books and read rather than continue a conversation. Also known as a Bilateral Booking.

At the Zig Zag last night Brian tried to talk to two babes, but ended up completely bookended.

Cheese bookend 

To avoid unwanted bowel movements half a block of cheese is eaten and the other half inserted anally, thus creating a 'cheese bookend'.

Matt had a long day of travel ahead of him so he bookended the cheddar so as to create a cheese bookend and to avoid shitting himself
