Donald Trump's (in)famous quote "Grab 'em by the pussy".

"Them" is plural, so their pussies should be plural too.

Grab them by their jersey.
since each player only has one (usually).
The same is:
Pat them on the back.
not:
Pat them on the backs.
Whereas:
Kick them in the knees.
is plural since each player has two knees (shins).
