stiffly stifferson

A person who isn't keen to light-hearted or fun jokes. More specifically, pranks.

I put rat poison in my boss' coffee and he got mad at me. What a Stiffly Stifferson.

Stiplify 

To specify a stipulation

Seriously, can we stiplify what direction our relationship will take?

Did we stiplify what conditions we agreed to?

stiffling

This is a combination of a "stiff upper lip" attitude and stifling behaviour towards someone else. Making someone do something without giving them a choice (they are stiffing them of a choice!).

A school assigning pupils to do an extra curricular activity. (YOU KNOW WHO YOU ARE!) The pupil has no choice and has to commit time outside school hours to the activity. The school is therefore being stiffling.
