When making a useless name, I try to make euphonious sounds that seem like they could be real words in some language, or real words said really fast.
insorum
in
so
rum
It has no meaning, but it sounds euphonious because of the vowels and consonants meld together well, or at least better than, say tsdflk. which I would imagine would be pronounced as tisedflik (incredibly fast), and isn't particularly pretty imo.
Some other random names
barkodha
inflegra
polhonis
and so on... ensoön!
Whenever I pick out a name I like, I google it to see if it actually exists. In the case of Insorum, it's apparently some kind of fictional drug on the MMO game EVE
