A very soft (mushy) bowel movement in which an individual wipes their anus over and over again without any great success, resulting in an itchy butt, and the use of a whole roll of toilet paper.
A Mushymushymoshmush involves the man cumming up a womans nose, then the woman blows her nose and has a nose bleed, all the snot, cum and nose bleed is put in a bowl and into the fridge. A couple of hours later, it is brought out and a tampon is mixed into this- add a bit of cat vomit and place it in your mouth, prepare for an indulgent kiss!
