Nip and tuck till crack of doom.

You wait. We'll nip this in the bud.

This is a little straw, and what you do is you just nip two corners here, and this becomes like a baby crocodile's mouth.

We may all think we're immune here because we can nip along to Tesco Metro whenever we like in the middle of the night and buy something... that whole system is in jeopardy.

He's like one of those weird chappies in India who dissolve themselves into thin air and nip through space in a sort of disembodied way and assemble the parts again just where they want them.
