Usually intended to describe the largest tower in medievil castles, it is now rather comically used as a euphamism for a penis.
I have a humongous bastille
Bastille is an amazing band from London. The members consist of Dan, Kyle, Woody and Will. They are called Bastille because Dan's birthday is on the 14th of July (Bastille Day). Dan is the singer, Kyle is keyboards, Woody is the drums and Will is the guitar/bass. They are known for their songs, "Pompeii", "Bad Blood" and "Flaws", but they have loads of other unreal covers and songs. In other words, they're amazing.
"I really want to see Bastille playing in the Indiependance festival in Mitchelstown, Cork." said Ben
