unrestrainable

Here her unrestrainable high spirits and levity gave great offence to the citizens.

And Missy, for some reason, grew sort of cross, too; she resented the other girls' unrestrainable hilarity.

Shock from a coated jar; perhaps an unrestrainable ethereal fluid yet unobserved; electric condensation.

The lovely, firm, red lips became creased from unrestrainable happiness at sight of him.
