A good friend, aka a homie. This word is used when either greeting or departing from your homie. For example, "Yo homie, what's up!" Likewise, "Alright homie, I gotta dip like a potato chip." This term can also be used when asking your homie a question or making a bold statement (i.e.) "Hey homeslice, how much cheddah do I owe you?" or "Homeslice, you trying to rip me off yo?"
A good way to remember this term is to conceptualize a pizza pie. Assume every piece of pizza is a friend. You like slices of pizzas in the same respect you like your homeslices.
Pizza slices = homeslices = homies
