Rainbow Kissing 

When a person shoves a potato covered in pickle juice down their mouth then the other person fills Their mouth with mayo and ketchup then the people both start making out until the potato explodes in both mouths causing a vortex to destroy the whole world.

Little Tim don't you dare start rainbow kissing so we don't lose that thick potato.
