Definition Wobble

When multiple parties are using the same word, but with different definitions, making communications confusing, cyclical, and ineffective.

"Bernie Sanders is a liberal!"
"What? No he isn't! He's a demsoc!"
"I meant 'liberal' in the context of American politics, as in, a term for the left in general."
"I thought you meant an economic liberal, like a neoliberal. Damn, definition wobble got us again!"
