A mild slang name for a penis, supposedly less offensive that cock, prick, or dick, it does not have the fecal connotations of dingleberry but is used to describe the penis in much the same circumstances by much the same people. In addition it can also be used as a mildly disparaging term for a person who has exasperated you by doing something atypically stupid.
"I had to rush like hell to get here on time. I was halfway here when I remembered I'd left the contract in my desk at home and had to go back for them, I felt like a right dooberry."
The fear when people genuinely like you and you can’t fathom why.
Wondering if they have you confused for someone you believe they deserve, someone who doesn’t have the qualities you hate the most about yourself.
When you look into my eyes, I’m struck by dolonia, and I’m sure you’ll leave me soon
The frustration that you'll never be able to understand another person's pain, only, ever searching their face for some faint evocation of it, then rifling through your own experiences for some slapdash comparison wishing you could tell them truthfully, "I know exactly how you feel."
