What Does SMT Mean?

SMT means "Simultaneous Multi-Threading" or "Sucking My Teeth."

Simultaneous Multi-Threading

In computing and online gaming, SMT is a technique for improving the efficiency of a CPU (Central Processing Unit). SMT is the process by which a CPU doubles parts of the core, in order to allow each core to run two instruction streams at the same time.

SMT may not match the quality provided by having a greater number of physical cores, but it speeds up the CPU, whilst keeping manufacturing costs down.

Sucking My Teeth

SMT is also used with the meaning "Sucking My Teeth." In this context, SMT refers to the action of literally sucking ones teeth, which is often done in spoken conversations and which indicates a pause for thought before responding to what has just been said. As in real life, SMT can indicate that the sender genuinely needs to consider what has been said. However, it is also very likely to be a theatrical gesture, employed humorously.
