A derivative of the word "mistress". Striss is a blanket term encompassing all of the female sex, including a female companion, a regular slay, a target female to take home from the bar, or simply a jogger/walker. Striss is often used in a slightly derogatory manner, especially referring to sexual promiscuity, or low intelligence/high crazyness
