Your hookah is covered with so much rust, you'd swear it was recovered directly from the wreckage of the Titanic. Unfortunately there's not much to be done about rust after a certain point. Time to ditch that rustbucket and get yourself a real hookah!
Your hookah tastes like every flavor of shisha you have ever smoked - with each session.
Flavor ghosting is an annoying problem. Ever bought a new hookah, loaded up a bowl of Double Apple (for example), and then every single smoke session after that all you can taste is Double Apple? Well, that means the interior of your hookah is basically stained with Double Apple residue; often this happens because the hookah wasn't cleaned thoroughly or soon enough after a good smoke session. Whatever the reason that caused your hookah to ghost a certain flavor, it is really difficult to "unghost" a hookah. It's important to regularly clean your hookah.
Your hookah is so beat up, it looks like it just survived the Hunger Games.
You lost or destroyed your hookah base, and decided to use Grandma's Urn as a replacement. Just get a new hookah. At the very least, replace your base already! It's the least you can do for Nana. Assuming you transferred her ashes into another urn.
You visited Turkey, and found a hookah that was made in the 1600s, so you think you found the Holy Grail. Pro-Tip: Centuries old hookahs are a nice novelty, but you have not discovered the Holy Grail. These super old hookahs often have airflow issues, taste like 200 years of dirt, or just don't provide a quality smoke session.
It's time for a new hookah.
