strop out

Ravi paused. Nora had once liked him, and he'd been a loyal friend to her brother. But, as with Joe (Nora's brother), there was a barrier between them. They hadn't parted on the best of terms. (He'd thrown his drumsticks on the floor of the rehearsal room and stropped out when Nora told him she was out of the band.)

I know the informal meaning of the verb "strop" but I don't know the meaning of "out" in this context. Does it mean Ravi "left the rehearsal room" angrily or is "out" a particle of "strop" there? If so, what does it mean then?

It does appear to mean the same as "storm out" (to leave the room in an angry way). "Out" indicates "go out of the room". The phrase isn't used in BrE, though. You might hear "stropped off" (meaning the same).

It's not a phrase I've heard in AmE either. I wonder if it's supposed to be a portmanteau of 'stomp' and 'storm'.

In BrE, "strop" is more often used as a noun.
