Holy lag!

[Crator]

Lag is also a laymen's term that means: Fail to keep up or to fall behind.[1] In real-time applications, the term is used when the application fails to respond in a timely fashion to inputs.[2][3] The most common use regards online gaming when the game doesn't respond in sync with the player's controls, usually due to a slow internet connection, server latency or overworked hardware.
Lag is also often used in reference to video games to describe the delay (or latency) between an action by a player and the reaction of the game

In the technology world lag typically is something you are describing when talking about network communications though.
