When a person/animal falls to the ground and starts to flop around almost like they are having a seizure... This could be due to an actual seizure, drunkenness or a bout of rofl due to some hilarity that has ensued among other things...
Dude... why was that girl flopping around like a fish on the floor last night?

She got so drunk that she started doing the bacon

Get the Doing the Bacon mug.
A phrase similar to "I smell bacon" indicating that a law enforcement officer may be in the vicinity. See Bacon

Usually asked to your partner(s) in less than legal deeds when you think the cops may be afoot but are not completely sure or don't see them. Can also be used to bring up the suspicion that somebody may be a cop to said friend.

Can also be used as a phrase to alert homies and ask them to look around for police activity in the area.

May have originated from the movie "Wayne's World" when character Wayne Campbell asks Garth if he smells bacon in front of a police officer outside a diner.
