Relative to the word "invertebrate". A boss or leader who has no spine to make tough decisions or stand their ground when confrontations arise. This leader will be influenced by the slightest pressure and will fold their stance instead of holding firm to believed opinions. A title holder with no self respect.
"I can't believe Urban Dictionary rejected my added definition of inverteboss. Guess it didn't have enough obscenities or sexual innuendos included in the description".
