What's on your mug?

When food is really good and you smack or same as asking is it good.

(Friend smacking while eating ) Me: damn girl, is it smackin'

When someone has taken ecstacy and after the energetic facet of the drug has worn down, the user feels like they want to sleep. They could even sleep on the ground in the middle of the city. Usually comes as an after-effect of a really energetic night then a few hours later you feel really tired. Probably because the energy is coming from no-where and your adrenal glands are putting out energy they don't have.

'What's wrong man?' 'Awww fuck I'm smacking hard.'
