When you sit down on the toilet and the gas builds up like an enigne's turbo spooling up and then all the boost comes at once blowing your shiteverywhere!
"The chili I ate last evening gave me the turbo shits so bad it was blowing out under the toilet seat."
When you run full speed at a girl while jerking off and when your about to splooge you jump and mega thrust as your splooging right into her face this will take skill and practice but if acheived will smack her right in the face at full speed and fuck her day up. plus you will laugh
When you need an energy boost and a good ol' regular chicken soup doesn't cut it, you may try adding some speed (amphetamine) to your soup for that EXTRA oomph.
There's also a gourmet turbo soup that uses cocaine instead of amphetamines.
You can also make turbo coffee, turbo choccy milk, turbo anything - just make sure you put enough uppers in it.
