'Thadtime' refers to ridiculously long time it takes for one named Thad to perform a task. All the while, time for Thad seems to move at a snails pace and he believes he can accomplish a huge amount of tasks in a very short time. Poor Thad is completely oblivious to the fact that he told someone he would be done in 10 minutes over 2 hours before. It is extremely unwise to refer to 'Thadtime' within earshot of Thad as it seems to invoke extreme agitation. Anyone who wishes to associate with him must be aware of Thadtime and adjust his/her life around it, as he will not acknowledge or change his Thadtime behaviour.
Thad: I'll be done with fixing this bike in 20 minutes. Tops.
Me: Ok, so I'll start dinner in 2 hours thadtime, then?
Thad: No, I just said 20 minutes!
Me: Ok, hun..sorry.
2 hours later.....
Me: Dinners done!
Thad: Ok, in in 5.
Me: (super quietly) ok, see you in the morning...
