To poke someone with one to four fingers in the anus. Only to be done with bottoms on while saying "SHASTA". or "I heard you like it up the butt" depending on the response if its a women you can tell their sex noise, if they like anal or if they are completly appauled. If it is a man you can tell if they are homosexual, bi-curious or Straight. It is possible to hear a mans sex noise while performing the shasta but it may be misconstrued.
Heather performes a "shasta" on Charlie. Charlie sqeals in delight. She obviously likes it up the butt :). Another example would be... Heather performes a "shasta" on Mini Zec Efferon. He jumps and smiles. He too enjoys anal. But do not performe the Shasta while in the presence of Mrs. Mechling for she will write you up, you will get suspended and you will be sent to MTI for your time of suspension.
