'tassium

Something that sounds dangerous, but may not actually be.
So many things that are actually dangerous end in "ium". Uran"ium", pluton"ium", stront:ium", etc. Then there are things that sound dangerous only because they end with that same "ium", like magnes"ium" and potass"ium".

A person that is 'tassium is pretending to be dangerous but really isn't, or might create danger for others or themselves accidentally.

For example, a wannabe gangsta brandishing a starter's pistol is 'tassium...until someone pulls out a real gun and shoots them dead!
