Fish breathing is medical slang for a sign of acute respiratory distress when a person gulps in air through his mouth in an attempt to breathe. It's so called because the opening and closing of the mouth resembles a fish periodically sucking in water. It usually means that something in the respiratory tract or the heart has gone horribly wrong (i.e. gunshot wound, multiple organ failure, pneumonia).
"The patient was fish breathing when we found him, he turned out to have a GSW to the left chest with hemothorax. We drained out all the blood and sewed him back up but the injury went septic and he died the following morning."

Inhaling steam from a hot pocket, and exhaling it, imitading the smellyness of stereotypical ghetto mexican's breath after eating a taco or burrito

Another Saturday morning condition similar to pisshead's pocket in which one's mouth still reeks of left over kebab from the (Friday) night before.

When you laugh so hard that you make that disgusting gurgle-y chuckle-y snort because you can't breathe.
