m33p

A term either derived from 'meep' which was said by roadrunner on an old cartoon series, or the noise that worms make if you listen really carefully. Orginated on an old mmorpg i played when i was 12-15, people just spammed "m33p" for about 2 days, because well they could.

A dweller(or infact anyone):"Hey"
Kestrel(me):"m33p"
A dweller:"??????"
Kestrel:"n00b"
