A weird sex act involving two people with their assholes facing each other so both holes touch. Each person squeezes out a huge long shit so they both collide like trains coming out of tunnels. Then the people ejaculate and cover themselves in the shit and cum so it looks like the flag of Latvia.
"Jim and I achieved the Latvian Train collision after 10,000 other successful attempts."
