When 'Shisha' (shisha/hookah) is used with verbs of movement such as 'gehen' (to go) or the preposition 'auf' (for/to), it usually refers to the social activity, not the device itself.
Wir treffen uns später mit Freunden auf eine Shisha.
We'll meet up with friends later for some shisha.
When referring to the device, typical verbs are 'eine Shisha rauchen' (to smoke a shisha), 'eine Shisha vorbereiten' (to prepare a shisha), or 'eine Shisha sauber machen' (to clean a shisha).
Kannst du mir helfen, die Shisha für die Gäste vorzubereiten?
Can you help me prepare the shisha for the guests?
Using 'Shisha' (shisha) to refer to the activity of smoking is colloquial. In more formal contexts, you would describe it more precisely.

Do we want to go smoke shisha tonight?
