Savannah's Wisdom
A STD (Savannah Transmitted Disease) in which a Savannah personally goes up to you and touches you on your shoulder, knee, arm etc and "Imparts her wisdom" on to you. Most victims find it very disturbing and a bit obsessive to gain this wisdom. Symptoms included but are not limited to: Stupidity, trouble in Geography, randomness, obsessive addiction to Tumblr, hyperactivity, the need to do gymnastics and the need to give other people her wisdom.
I feel nasty, Savannah's Wisdom makes me feel stupid already.
