Bum Tunnel

The term used when two people of any sex create a tunnel by pressing their bare bum cheeks together, usually for the purpose of a third male party to insert their penis for sexual pleasure.

A play area style that is a mix of corner camping and aggressive movement. In order to tunnel rat properly, you must move from corner to corner fast. Never sit too long in each corner and don't move too aggressive or you'll fall out of the range of tunnel ratting.

These guys are pushing aggressive, I'm going to start tunnel ratting to counter them

Quantum Tunneling

Quantum tunneling refers to the phenomenon in quantum mechanics where a particle has a finite probability of crossing through an energy barrier or potential barrier despite lacking the necessary energy to overcome it based on classical physics. This behavior arises due to the wave-like nature of particles at the quantum level. Quantum tunneling allows particles to "tunnel" through barriers, enabling them to reach regions that would be classically inaccessible.

"In quantum computing, qubits can exploit quantum tunneling to tunnel through energy barriers, facilitating more efficient computation processes."
