A dick circus is performed when a male and female are in bed together and the female goes under the covers to perform felatio, which makes the covers over her head look like a pitched circus tent. This is also known as a Pee-Pee Tee-Pee.
Will was with his boyfriend and said "You're the star clown of my dick circus." Jeffrey then replied "Just call me the ringmaster!"
