Composite of the words 'Probability and Suction'. Probsuction is often used as a way of describing a force that causes a fluid or solid to be drawn into an interior space or to adhere to a surface because of the difference between the external and internal pressures. The probability between the suction and release could vary depending on technique and skill.

Bob: Well it depends on how powerful the probsuction is.
