This word/s is spelt in italian as "mamma lucca" shortened to one word. "Luccare" is a verb used in mid region and southern dialects meaning to shout or to call loudly. If you're a mammalucca (can be spelt phonetically in many ways), you are someone who always calls out for your mamma. You are a mamma's boy.
That mammalucca never goes out, he's scared mate, scared!
