To show anger as described in point III is only allowed under the following circumstances.
- No Dude should be concerned about weather another Dude does wear the Dude kit or not. If a Dude has a problem with your kit this would be uncool and can give reason for anger.
- To get ash of a dead friend blown into a dude's face is uncool and can give reason for short anger. Ash of people the affected Dude did not know is okay and an exception of uncool stuff.
- Calling another Dude by his or her forename and surname is uncool. Calling a Dude Mr., Mrs. or any other formal appellations is the highest level of uncoolness. After such an uncool happening it is possible to explain the non-dude in an angry fashion that your preferred name Dude is.
