Like a dingleberry (a resistant piece of fecal matter stuck to your anal/gooch hair, very hard to remove, etc) a lingerberry is the guy/girl of the group that is generally unwanted. They are just standing around, being antisocial, not contributing, and being all around weird. Usually, no one has the heart to tell them/ask them to leave. Lingerberry's always include themselves in other's plans, completely uninvited.
Miller: Why's he here? He's not even doing anything and no one invited him, he won't leave us alone!
Zerab: I know, I want to tell him but I don't want to sound rude. He's such a lingerberry, it's so annoying.
