Similar to a 'Dohdle', but generally reserved for small animals such as chinchillas, dogs and animated characters. Mumpers generally do not understand the circumstance in which they find themselves as they are so cute and helpless.

Can also be combined with 'Dohdle' to make 'Mumper-dohdle'.

Suffixes include, but are not limited to, "man", "woman", "dohdle", "bumper", "chumper", "trumpet", "face".
