blabalanche 

A torrent of words that you are not interested in hearing.

Usually occurs during phone calls, skype calls, and powerpoint presentations

The only reason I don't call my parents is because a blabalanche is sure to commence!

slackalanche 

The deluge of messages in Slack that cause a particular one to get lost thanks to Slack's feature of marking a message as read once it is glanced at.

Sorry, lost this in the Slackalanche and am just getting back to reply. ¯\_(ツ)_/¯
