Blockages

I feel bad for you OP, I really do. however, ydi for not asking for clarification first.

He didn't want to embarrass her by asking since she didn't clarify that her sinuses were plugged. Most people don't clarify stuff when it's about their private parts or the situation is embarrassing

Ehh, OP kind of guessed right. Plugged up I think of Constipation, Stuffed up I think of Sinuses. I personally don't think OP's GF used the correct general term.

Similarly, OP’s gf should have clarified. The idiom for constipation is “plugged up,” the idiom for sinus problems is “stopped up.”

The usual term for troublesome sinuses in my neck of the woods is blocked. The only use of plugged up I have ever heard is constipation related.

I think SHE deserved it for not giving clarification

No—not butt-plugged up!

Okay I totally would’ve assumed the same thing

Well, at least you have them for future need.

What medicine do you take after a gang bang?

Plugged up means the nose is stuffed up. Backed up means you can't poop. It's not that hard to figure out.

Biiiiig difference between "all bound up" and "all plugged up!"

IDK if u're for real or just joking but this is too good either way
