-sies

Suffix added to the end of almost every word. Used mostly by 40 year women talking to their children and/or dogs, or drunken college whores in a desperate attempt to sound more cute, less riddled with STDs and premature, substance induced age.

SI

Abbr. for "self-injury," also known as self-mutilation. Most common form is cutting, but may also include burning, bruising, skin-picking (excoriation), and other behaviors. There is no single cause for SI. SI is most common in women and tends to persist for years.
As a result of overwhelming anxiety, she turned to SI as a coping mechanism.
