Top Definition
A type of slow moving mammal that has been around in the Lake District since the last ice age.
There are two varieties of riellypants, two-toed and three-toed. While they may look similar, evolutionarily they are not closely related.
Both types of riellypants live in the forests of Cleator Moor, spending almost their entire lives in the bushes.
They are nocturnal animals that spend much of their day sleeping.
They have been closely linked with the typical American Sloth... like Sid of Ice Age... He's my favourite...!
Wow look at that thing in the bushes dad, what is it? Well son, its either a Sloth thats got lost, or its a riellypants...!
