The feeling one gets when
thinking about writing their thesis, usually making them
feel physically and/or mentally ill.
Symptoms can include, nausea, lethargy, incoherent conversations and sometimes momentary lapses of motor skills (eg. walking).
Without treatment thesisitis can result in excessive desk chair racing and
may result in injury.
Student: Man, every time I think about my thesis I feel
sick.
Friend: Well maybe you've got thesisitis, it's probably a good idea to take the day off.
Student: Today I rode an
elephant backwards up the stairs.
Concerned friend: Pretty sure you have thesisitis... I'm just gonna keep my distance in
case it's contagious.
