When three girls, usually friends, stand together in a triangle so close that their boobs touch. This happens when they are in a public setting like a party and they need to talk privately.

This can also be done on purpose for fun or as a joke.
"Hey girls, come over here. I have some great gossip!"

"OMG we are in a triangle boob touch right now!"
