A Morgan
A Morgan is like a golden retriever who also has a PhD and will give you a titty just to make you feel better. They're not gay, but they'll show you everything if it means keeping you happy.
My Morgan showed me her titty during a math test just to help me pass.
She told me she'd show me her titty if I passed my driver's test.
At the party, Morgan pulled out her titty like it was a trump card.
