Horn Blowing 

The sexual act of a man inserting his penis into the anus. While thrusting himself into a male or female anus the other partner farts. This act is considered blowing your partners horn.

Horn Blowing is when my boyfriend and I are having anal, I squeezed his stomach and he blows my horn.

Doppler-effect horn-blowing 

Da annoying dual-pitch "Beeeeeee-yuhhhhhhhh!" dat you hear when some dumba** motorist roars past you while engaging in an "extended honk". Okay, okay --- so maybe he's "just trying to be friendly" by saying hello to a familiar face by the roadside (you), but as gas-station attendant Dale says in the Red Green Show episode, "Hurricane Doug", it's far more cheerful/polite and less startling/grating on the eardrums to just briefly "tap the hooter" a couple times as you go by.

And incident of Doppler-effect horn-blowing can be even more annoying and emotionally draining (i.e., it can become a Droppler effect sometimes) if you either (1) do not recognize whoever it was who honked at you, and so you are left to wonder "who that might have been" and/or if he possibly mistook you for someone else while your back was turned, or (2) don't have a clue as to the driver's reason for honking at you, and so you are left to wonder what you might have been doing that caused him to either notice or be upset with you. Plus of course if there are one or more other people in your immediate vicinity at the time, you may even be unsure if said extended honk was actually "untended for you", or if the driver was noisily "addressing" someone else nearby --- or all of you in general --- instead of you personally.
