BSH
In the game Left 4 Dead, while playing as infected, the team Booms, Smokes, and then Hunts in rapid succession. It is considered the most effective and efficient method of killing the survivor team.
**The Round Begins**

Harbinger: "Alright, everyone get set up."

The_Unseen1: "I'm in position for the BSH."

Sir Paul: "I'll boom them from up-top, you good to smoke?"

Harbinger: "Yup, and Unseen with Hunt last."

The_Unseen1: "Booyakasha."
