Tommi Wet is the juice from tinned tomatoes
When in a breakfast cafe ordering a sandwich and you want for example bacon, egg and tomato but you don't want the lumps of tomato you can ask for "Bacon egg and Tommi wet"
The act of putting all of your fingers in your mouth then placing your soggy fingers into somebody elses mouth.
Every time I yawn, papa hits me with a fresh Wet Tommy.
