A mythical creature created by putting all four of your fingers together side by side then putting your thumb between the bottom of your index finger and middle finger to make a mouth shape. Nim-Nims usually spend the day wreaking havok or tending to their nests. They move by floating through the air and bobbing up and down at the same time. They eat monkeys because they cannot find sandwitches.
Every time your pick up a small or thin object your hand is in the Nim-Nim position.

NIM is the revamped, transformed and self-configuring extraterrestrial aquatic lifeform of Naim.

According to Stalinist folklore, the founder of Fishism was bitten by a Tenualosa ilisha (Bangladesh's national fish) whilst copulating a couple mermaids in the LSE library, and thus ever since has been shapeshifting into aquatic species.
Once a NIM always a fish, once a fish always a NIM.

NIM can also be used in suffix form.
