Cartoon by Bill Schorr
If you hang out somewhere, it means that you just spend time in a particular place not doing anything really special.
“Come to think of it” is an informal expression that means “When I consider the matter” of “On reflection.” Take at look at this example:
“Come to think of it, that road back there was the one we were supposed to take.”
If you pitch or throw a fit, you get very angry and you express that anger!
