Heat is the stage of their reproductive cycle ( pre-ovulatory period - estrus ) when the woman feels more attracted by men, in order to get pregnant.
"The woman is permanently attracted by men, but, during their heat, that attraction is even more intense".

Heat can be used a few different ways.

1. Used as a synonym for "gun"

2. To describe temperature.

3. To describe something that was intense. (Basically a synonym for "Intense" generally when the scenario is something that could get you in trouble.)
1. "dawg we gotta confront them dealers tonight. make sure ya'll are packin heat"

2. "Gee willikers zip-a-dee-doo-dah Batman. My teeth sure are sensitive, whether it's to the cold, or the heat!"

3. *Thieves just robbed a bank and ran into an ally way. The swarm of cop cars drive right past the ally in which the robbers are hiding, and do not see the robbers.* "Whoa dude, that was heat. Those cops almost caught us! We BARELY made it into this conveniently located ally way in which we are currently hiding in."

When an animal (humans included) is so horny and eager to mate, that they'll hump whoever comes along.

Some people think that only females experience this state, but male animals also have a reputation for being achingly randy.
"Great...! Just great! We forgot to neuter our cat, and now she's in heat! I can't stand the howling!"

"While in Frankfurt (appropriately), I once asked a German storekeeper for a 'heißer Hund'- literally 'a hot dog.' He burst out laughing, as 'heißer Hund' in German suggests a dog in heat." -Richard Lederer
