The friend that never orders anything at Mickey D's for various reasons, (low on cash, diet) but will never hesitate to snatch some fries or ask for a sip of coke
Also means to mooch off someone's McMeal and to overstay one's welcome on the tray
Dennison is so cheap he even asks for handouts when people order off the dollar menu, what a McMooch.

I didn't feel like ordering so I just McMooched off Chris until I was booted from the table
