When the lip of a ladies clam hangs out of her panties and clings to her leg like bubblegum. May also refer to the appearance that closely resembles a ragged used up piece of big league chew clinging to her inner thigh.
As we walked up a hill on a long hot humid day, my girlfriend leaned over and whispered 'I have Clam Tongue Bubblegum'
When a woman's Labia Minora sticks out past the Labia Majora, kind of popping out like 👅. This kind of resembles a clam sticking out its tongue.
A: Ummm what's that hanging from her coochie?!?
B: What, oh that?!? Yeah she's got that Clam Tongue
