Nonvitation 

A non-invitation a person gives another (to an event, party, etc) - with the hidden intention that the non-vited person will not attend.
A nonvitation is usually given out of politeness.

When Cynthia bumped into me and Michal in the street - she invited us to her birthday. Cynthia is Michal's friend but not mine, so this was probably a nonvitation.

Nigvitation 

an invitation, but not. can be used when you are trying to be nice by inviting
someone, but have no intention of really following through if they accept.

A girl invited me to meet up with her but when it came time to meet her she was nowhere to be seen or heard, I guess it was just a nigvitation.
