The hello and goodbye is a routine usually preformed by a girlfriend or wife where she both starts the sexual encounter with a cock in her mouth(hello!) and ends the encounter with the same cock in her mouth(goodbye). (In between that period she is fucked lavishly) Just a standard blow job does not count as a "hello and goodbye".
My wife woke me this morning with The "hello & goodbye". And then she went to work and I went back to bed.

Situation in which you encounter someone you know - especially someone you have not spoken to in some time - have a conversation then depart, only to immediately encounter the person again, resulting in social awkwardness.
Former neighbours A and B run into each other at the mall and chat for a while, following which:

A. It was nice to run into you!

B. It really was - send my regards to your family.

A. Take care!

Five minutes later A and B run into each other again in the parking lot and smile sheepishly at the awkward post-goodbye hello
