I'd hope that, when making a title (not just texting a friend), more than whether it causes ambiguity counts. Would you be equally ok with it if they said "there" when the correct word was "their"? This sort of word does not become compounded in the way "rain coat" can become "raincoat". There isn't a single example where the verb form of any of these, as a single word, is considered correct: backup carryout checkout comeback cutover cutoff failover handout knockout lookup lockdown login logoff logon logout meetup meltdown pickup rollback rollout rollover setup showoff shutdown shutoff signin signoff signout signup slowdown startout startup takedown workaround workout
