okay so clutch is like... "coming through in the clutch." something helpful, especially at a time of distress or just when something is needed. So lets say your at a party and it goes dry, and your friend walks in with a bunch of alki. You can say, that was so clutch! or even better... u can just say.. "Clutch Cakes." Cakes being the term of grandiosity and even being "sweet". i guess. so its better than just being clutch.
Also can describe when Cup Cakes are phenomenally delicious.
