Is hoarding toilet paper a new form of mental illness?

Old form it's called OCD.

Whats your blood type ? I bet your blood type is O

To answer your question. No. Some people legitimately can afford $10.99/1 roll

Yes it is. It is very serious.

They are hoarding more than toilet paper. There was only 3 bottles of dish soap at the store yesterday, no toilet paper or bleach, of course. The green leafy vegetable section was sold out.

It's a new way of expressing the same feeling of fear by "not getting enough" of love, of food, of air, of whatever. It is also a fear of abandonment during this coronavirus pandemic.  Yeah, the toilet paper will get up and walk away from you. 

It’s more a defense mechanism ppl are using in light of fears they’ve never contended with.

New form of stupidity is more accurate.

Stupid profiteers are now stuck with a lifetime supply.

No.  It's just a reaction to the same old idiocy that always drives certain people.

Shouldn't you have asked this question on the day people stood in line at Costco for toilet paper rolls
