Connipsis is a combination of the words ellipsis and conniption. It is indicated by a series of three exclamation marks "!!!". A connipsis is typically used in internet forums, SMS messages, email, IRC, and various other forms of electronic communication. While a typical single exclamation mark indicates strong feelings or high volume, an over usage of the punctuation mark indicates extreme emotion bordering on a conniption fit.
Typical usage of a connipsis:
OMG Becky!!! Look at her butt!!! It is sooooo big!!!
