In the early days of computing, all fonts were mono-spaced, meaning that each letter occupied the same amount of horizontal space on the screen. This made it difficult to create aesthetically pleasing typeset documents, so users resorted to using weird fonts.
Weird fonts are fonts that don't follow the standard rules for spacing and alignment. They can be difficult to read and understand, which is why they're usually used for special effects or as a way to stand out from the crowd.
Some common weird fonts include Comic Sans MS, Brush Script MT, and Curlz MT. While they may not be suitable for everyday use, they can be a lot of fun to play around with.
