A simple mixture of dirt and water. The viscosity of the mixture can be altered by adding or removing water, though the latter is substantially more difficult. Its uses are endless, ranging from pigpen groundcover to the primary ingredient in an easy to make pie.

The compound was first "invented" by the homo hobilis as a defense against unwanted female attention. He found if he flung it at them, he could ward them off. This ultimately proved contrary to his survival, however, so he began flinging it at those who encroached on his females. Also, those who stole his females received a rainstorm of it on his dwelling. This practice continues today, and occasionally excreted matter is added, for the sake of odor.

Nowadays, it is commonly seen as an obstacle to be avoided, especially by vehicular traffic. Nonetheless, it is still enjoyed by "offroad" traffic, and people playing tug-of-war. Thus, it can be deemed one of early man's most significant contributions to modern society, and grouped with fire and bacon.
Today I poured water into dirt, and pondered the resulting mud in both a scientific and philosophical manner

Multi-User Dungeon.
Many still use this term to refer to a variety of online RPGs, but for the most part, a MUD is completey text-based. Usually the movement of one's character is bound by 'rooms,' or quadrants of area which determine where you are and what you can interact with. Movement generally uses abbreviations for the cardinal directions (n,s,e,w) and sometimes 'in,' 'out,' 'up,' 'down,' etc.
While macros, keybindings and aliases can be created, from the get-go, most commands are typed in, i.e. STAB RAT or BUY SWORD.
MUDs are mainly critisized for being overtly "nerdy" or requiring too much imagination and typing skill. Usually there critisisms come from nearly illiterate RuneScape junkies or snobbish WoW addicts.
