Shopper vs "Hommer"?

I was trying to explain to Nicole the meaning of the word "shopper".

Me " A shopper is someone who is shopping at a mall, or even a supermarket"
Nic " Oh, so I am a "hommer""
Me " Huh? what is a "hommer"?"
Nic " I am staying at home now...so I am a "hommer""
Me " No no no....."

How creative of Nicole !
