When you're doing a girl (she's on bottom) and you hold her by the throat to get a better grip. Due to the pressure on her vocal cords, instead of moaning, she can only make sqeak-like noises. Kinda like a rubber duckie.
The bitch pissed me off so I held her by the throat while fucking her until she rubber duckied.
