Pelicans Yawn 

An extremely large vagina.

Her cunt is wider than a pelicans yawn, it was like shagging a wizards sleeve.

Pelican's Yawn

A vagina so large it can hold up to 50 lbs of fish (or luncheon meat).

Katie: "That girl Dom did last night apparently had a massive pelican's yawn."
Jess: "Really? Not as big as mine, I bet."
