In IBS, there may be increased mucus production by the lining of the intestine. That mucus is then passed in the stool. Mucus is more often associated with diarrhea-predominant IBS than with constipation-predominant IBS or alternating type IBS (IBS-A).
MUD. n. A computer program, usually running over the Internet, that allows multiple users to participate in virtual-reality role-playing games.
Since most mud runs are followed by a celebration of your achievement and some partying, so bring a change of clothes. Make sure that you have directions and are punctual when arriving to your event. They will not wait for you if you are late.
