--- According to Eric Partridge's Dictionary of Slang and Unconventional English, the expression suss out originated in Britain in the 1960s and remains chiefly British slang, although it's becoming more popular in other English-speaking countries.
Most of the major dictionaries suggest that suss is simply a shortened form of "suspect" and there is some evidence that it was used as far back as the 1920s as a verb meaning "to suspect." It has also been used as a shortened form of the noun suspicion (The police arrested him on suss), as well as a noun meaning knowledge or understanding (He's got suss).
Like many slang phrases however, the exact origin and timeframe of this expression is, shall we say, difficult to suss out.
