When you are driving down a road, and the trees form a tunnel over it you are in a tree tunnel.
the tree tunnel was so dark, i coulndt see a thing and almost crashed my car!
A top of shotgunning
two people make a tight tunnel out of their hands and the gunner blows while the receiver sucks.

A tranny tunnel is what you get when a man, in pursuit of becoming a woman, splits his penis like a banana peel and folds it inside out into a wound that constantly tries to close itself.
Alternatively, it is the path for a transmission to be routed.
Tom needs to hit up the dilatation station for maintenance on his tranny tunnel.
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."
Quick rough anal sex with your partner
Bob and I did some aggressive tunneling while the baby was napping today.
When a male sits naked on top of their naked partner and farts directly into their butthole, this creating a “French Tunnel” effect
Had some really great sex and afterwards gave her a massage, and in the middle of the massage I gave her a surprise French Tunnel , she was mortified
1. What Mr. Happy has (i.e., his "vision" is always focusing on just one thing --- specifically, a gal's "love-tunnel").
2. What the vengeful and intently-gazing-straight-ahead Biff Tannen was experiencing while trying to run down Marty McFly in the underground causeway, and therefore he never noticed Old Man Jones' fertilizer-truck in time to avoid colliding with it --- yet again --- and consequently having himself and his car covered with the truck's messy contents ("MANURE!! I hate MANURE!") a second time, mere hours after having gotten said beloved jalopy back from Terry's garage which had cleaned it out from its previous encounter with said poop-hauler.
I always slow down a bit and drive extra-carefully through mountain-tubes and other underground traffic-passes, since it's notoriously easy to unwittingly get "tunnel vision" when traversing said claustrophobic motoring-routes.
