Traditionally in software, Easter Egg is a hidden or secret message or a function. In X-Bot's case those are special messages that appear if triggered correctly by the user.
By default, those are enabled. However, admins can disable those by using "x.text_response off"

This easter egg is more of a convinience to users - the bot responds with an actual lenny face ascii emoji if you type one of the following:

• lenny face
• le face
• lenny

You can also add "tiers", e.g.: "lenny t3" (You can use t1-t4) that would make it bold and/or slanted (each tier adds '*' surrounding lenny face)

This one was mainly designed for mobile users since they dont have /shrug command. To use, type one of:

• shrug
• shrug face
