Should I list my current job first on my resume if it doesn't apply to the job I'm trying to get?

I am currently a housekeeper, I just got the job to pay the bills while searching for an administrative assistant job. I'd rather not have it on my resume at all since it doesn't apply, but I also don't want my prospective employer to wonder what I've been doing for the last 6 months. They always say to put your most recent job first, should i do that or should i put the most relevant jobs first? Also, should I mention somewhere in the description of the housekeeping job that it is only a "survival" job?
