give away a secret
spill the bins
something that is unlikely to happen
pie in the sky
a person spending too much time on TV
a couch potato
behaving strangely
be out to lunch
say nice things in order to get smth
butter somebody up
to receive very little money
be paid pea-nuts
in a few words
in a nutshell
to go badly wrong
go pear-shaped
be full of energy
be full of beans
