'Honey Boo Boo' -- Naked Photos of Uncle Poodle for Sale

Honey Boo Boo's Uncle Poodle is sending pics of his schlong to random men on the Internet and name-dropping HBB -- all in the name of getting laid -- this according to a man who is now shopping the dong shots to media outlets.

TMZ was offered the pics which show a naked man who appears to be Uncle Poodle ... in the shower. According to the seller -- a man who lives in Georgia -- Poodle sent them earlier this week on the gay social app Grindr.

Poodle -- real name Lee Thompson -- is frequently featured on "Here Comes Honey Boo Boo" and is openly gay.

The man selling the pics claims Poodle dropped HBB's name almost immediately during a chat ... saying,"So you know who honey boo boo is? That's my niece."

The seller claims there was no hookup.
