Does anybody remember Rich Hall and sniglets?
I have been carrying one in my head like an 'ear worm' for years.
Showertia - That force which makes one put off getting into the shower (especially on weekends) and then prevents one from finishing the shower and drying off once one has started a shower. An object out of the shower tends to remain out of the shower and an object in the shower tends to remain in the shower.
Also applies to empty shampoo bottles.
