An imposition of speech, it is the deliberate and selfish use of communication to communicate nothing.

A speech fart can be written or spoken. It contains no wisdom or wit, imparts no useful information, and is often rude or obnoxious. Speech farts are an imposition on others, serving only to satisfy the speaker's own selfish desire to have his or her words seen or heard by others.
Examples of common speech farts:

On an online forum: "IBTL"

In a comments list: "First!"

On Twitter: "Having eggs #breakfast"

In a Facebook status: "John Smith sup"

On the golf course: "It's in the hole!"
