when a couple (only looking for a fling) have sex without a condom! they're both fucked.......likewise!

A situation in which two states have enough weapons (typically nuclear) to ensure that should one launch an attack the other would be able to respond in a strong enough way to destroy the attacker. Both would be destroyed.

This situation is supposed to prevent either side from launching such an attack.

The Cold War between the USA and the USSR in the 20th Century is an example of such a situation.

Where people kill each other at the same time in 1st person shooters. Very annoying.

A term from the Cold War: Because the Soviet Union and the US could destroy each other peace was maintained by theis "mutually assured destruction."

The result of two or more gay guys going, without proper preparation, at each other's ass.

The term for two people, both post curry, who fart at once.

The state of being in which two people both cock block each other into the friend zone even though they are both attracted to and want to be with each other.

They are then relegated to the state of perpetual friend zone with much regret yet they never know what it is that they failed to achieve.

Thus these two attractive people are forced to for ever interact and want yet not connect.
