Wankie Doodle

When you administer a pecker slap to your partner, followed by plugging one nostril by sticking your wankie in there blocking the air flow of one side of the nose; so that when they/them breathe it creates a whistling sound. Then, using your non dick-hand you can hold over your "instrument's" nostril plugging and releasing the nasal cavity like a trumpet to the tune of Yankee Doodle.

Before the couple enjoyed some coitus, Roger decided to give Marsha a proper Wankie Doodle during foreplay which he has renamed "Band Practice."

Pam - "Marsha, are you having trouble breathing?"
Marsha - "A little, Roger performed a Wankie Doodle on me last night, and i have been congested ever since."
