A guy who always accepts an invitation for pizza, never to return the favor. Will smoke your cigars even though his humidor is full. Will drink your alcohol first, especially skinnies, so he can take his home. He is 85 true story!
Does that mooch have to be invited to the draft again? Drank all my beer, smoked all my cigars, and did not even chip in on pizza.

In the UK mooching means going for a walk (usually looking for somewhere to eat) often while drunk and/or stoned.

In the US mooching is one person taking advantage of another.
(Two guys drunk in a tent in England)

John: "Where's Dave gone?"

Jack: "He went mooching off in that direction a couple of minutes ago"

(Two guys talking about friend's girlfriend in America)

John: "Dave's just bought his girlfriend a new car"

Jack: "She's just mooching off him coz he's rich"
