Guido doorbell
Guidos, frequently too self important to actually get out of their cars, or even call someone when in front of the house, beep their horns to let the person inside know they have arrived. Perhaps they are under the assumption that everyone else on the block is deaf, or wants a good look at their all around dark tinted windows on a white BMW.
I wish that Dickhole would stop ringing the guido doorbell and just use his phone.
