An Academic Look at BF4L

BF4L is defined as a cyber term because some of its characters are used as substitutes for letters.

Most cyber terms were introduced to reduce the number of key strokes required to write the word, but since the arrival of predictive texting and keyboards on mobile devices, this efficiency is no longer required. Nevertheless, cyber terms are still regularly used to make messages more entertaining or to express individuality.

Cyber terms differ from icons because they are not pictorial representations.
