Sequention
Term used during a toast when there are so many people present it becomes awkward and too time consuming to touch everyone's glass with your own. Saying "Sequention!" after a toast implies you have clinked glasses with each and everyone there.
(Someone raising their glass at a gathering)"Here's to having such great friends!"
(Raising your own glass)"Sequention!"
(Everyone else)"Sequention!"
(Raising your own glass)"Sequention!"
(Everyone else)"Sequention!"
