Mandaparty 

A social engagement you wouldn't choose to participate in on your own, but are required to attend due to professional or familial obligations. Mandatory party.

I don't even know my cousin's neighbor's niece, but I got a gift because it's a mandaparty.

mandatary 

Being 'asked' to volunteer, but it is actually mandatory. Being 'asked' is just a pleasantry. (see also: volun-told)

"They're asking us to volunteer for the event at work tomorrow."
"Man, forget that shit."
"I forgot to mention, it's mandatary."
