Someone who always is begging and stealing food. Example at the caff table if someone every day comes and asks for food or takes your pizza when you are not looking. They are usually very nice and you know you love them.. but its not their fault if they have gross lunches and they look for nourishment in others :) Always be generous and when they ask for gum dont lie and say no cause thats not nice. Rude if you call them freeloaders.
"Oh look its Julia coming to ask people for food again, she is such a mootch".
"Run from the mootch!"
"Hide your food, the mootch is coming"
