L337 Train
The L337 Train is the sound of a train doing a face plant into a hill while it cusses at the sky.
My dad yells at the radio: 'L337 Train, you're the best!'
My sister texts me: 'The L337 Train just made me laugh so hard I peed.'
My crush sends me a message: 'I heard the L337 Train and it made my heart go w00t w00t.'
