its wen you are running and at every step you are taking you are farting
ahhh wats that smell.
its that bitch that passed by he was running farts
Where you have to fart while you are running. When you fart, you can't stop farting.
This is also caused when you have to fart and attempt to hold it in and then you start running.
That was the worst 100 meter sprint I had to do, I had the running farts the whole way.
