The term samisfied will be used, if Sam has successful sex with a hot girl (at least a 9 on the scale to 10). It can only be used if the girl really enjoyed the act.
Samisfied can also be used as a pick up line. Check the example.
X: How was your night yeasterday with Sam?
Y: Oh damn I got samisfied!
As a pick up line...
Sam: Girls are you ready for some samisfaction.
