The act of checking your anus and undergarment after farting a lot. In essence, it is making sure you did not
shart.
The word "sheck" is a combination of the
words "
shart" and "check".
Jerry has been farting all day; he better
go sheck.
Person 1: "Is Jerry taking a
piss or a dump? What's taking him so
long?!"
Person 2: "Nah man. He is just shecking."
