MBS

Mouthy Broad Syndrome (MBS) affects people possessing two 'x' chromosomes. Symptoms can include:
- Not shutting the fuck up.
- Telling other people your private conversations or actions.
- Flapping of the mouth with no meaningful things coming out.

Treatment of MBS is usually as simple of administering one or two sharp blows to the person affected. If this does not work seek medical attention immediately.

My wife/girlfriend has been diagnosed with MBS. The back of my hand is getting really sore.
