Hi there!
There’re some idioms i can’t understand like in these situations:
-My uncle is A COUCH POTATO and he’s always glued to TV.
-Elena thinks her new WAP phone is the best thing SINCE SLICE BREAD.
-Pierre works on the checkout at the local supermarket. They PAY HIM PEANUTS.
Can anyone explain them to me, please?
Thanks in advance.
