when you are taking up a whole seat
for example, and won't move up to let somebody share it with you, much like rose on
the titanic when she doesn't move up to let jack on the
floating door, resulting in his death. BOOO ROSE!
(when someone is sprawled out, taking up loads of room on a couch,) "
oh come on budge up a bit, don't do a rose!"
OR
i couldn't sleep
last night because (
insert name of person sharing a bed with) was doing a rose!
