Pounds per square inch.
If used in the form "That person has a high PSI". It is a sexual reference saying there ass or another part of the body where a penis can be inserted is capable of taking alot of pressure, or quite a hard pounding. Can also reference to the largest penis they can fit in their ass before the pressure gets to high and rips it.
