FOUP stands for "Front Opening Unified Pod" and is used to carry wafers around in a semiconductor factor, which is called a fab.

From Intel, "Front Opening Unified Pod is the specialized plastic container that carries the wafers from one process step to another in a controlled environment."
Has the FOUP of wafers been delivered to the tool yet? It is holding up the assembly line if it doesn't get here soon.

Get the FOUP mug.
A foup is just what it sounds like. It is not a substitution for the so called great "F" word. It is a homage to the everlasting awesomeness of everything. Foup may be used in context and out of context. It is also a word that becomes one with the OM.
"You foup."
