The withholding of consonants in words. This is especially true of a g after -in, as in "swimmin" instead of "swimming". Also very common is the h after t, as in "dat" instead of "that". It can be taken to an extreme as in "Prez Clin" instead of "President Clinton". Consonantipation is becoming more and more common as people get lazier and lazier with both spoken and written communication.
