TENTITUS 

The aftermath of sleeping for one or more nights in a tent alone or otherwise.

I went to Glastonbury this year. The first night of sleeping in the tent, you wake up feeling horrible due to the temperature inside being 1000 degrees.

When a person is sick for reasons of missing a test on purpose.

Teacher: Why isn't Jeremy in today?
Student: Oh, he told me he's got a bad case of testitus.
