A tomson is a hairstyle that is a direct result of not showering for a minimum of two days. It may appear to be a new type of soft pomade, but upon closer inspection, you will find that it is just a general lack of Hygiene.

A tomson is not to be confused with the family name Thompson, which is a true and respectable family name.
