Long time, no see.
to ‘become’ temporarily crazy for something.
go crazy, mad, nuts
to say that something sounds familiar
To ring a bell
to be ready to take action
on the ball
to be the latest fashionable thing
a craze
to be exactly right about something
To hit the nail on the head
suddenly and unexpectedly
Out of the blue
the story is too long and don’t want to talk about it so you say...
it's a long story
To summarize your story you say
To cut a long story short
at the unexpected ending to a story you can say
end up
When you have a good time you can say
to have a blast
to be very bad
awful
to be very inconvenient
To be a hassle
to describe a task which is very annoying
To be a pain in the neck
