What is drain current in MOSFET?

The drain current below threshold voltage is defined as the subthreshold current and varies exponentially with Vgs. The reciprocal of the slope of the log(Ids) vs. Vgs characteristic is defined as the subthreshold slope, S, and is one of the most critical performance metrics for MOSFETs in logic applications.

Which way does current flow in a PMOS?

In an NMOS electrons are the charge carriers. So electrons travel from Source to Drain (meaning the current goes from Drain > Source.) In a PMOS holes are the charge carries. So holes travel from Source to Drain.
