Suss is suss, and is used as a synonym to something being cool, but can't be overused or else it turns wrong. Things that are suss include your phone charger working when before it didn't, the smell of a fresh pizza box opening, and getting head in the school bathroom. Someone who says they are suss or that they "have sauce" qualify as anti-suss, and can be seen as a little gay. Being a little gay is suss, but actually being gay is kinda anti-suss.
