2.
Celebratory fellatio
"Congratulations, I think we should celebrate this with a spot of celebratio!" - meaning, something positive has happened, therefore celebratory dick sucking should commence. For example:

1. Pass driving test, get dick sucked
2. Come home from Afghanistan, get dick sucked
3. Has it been 25 years since Windows 1.0 came out? Lol at Steve Ballmer, and get your dick sucked...
4. Something else... and this is key: Get dick sucked.
