That word is also used in other parts of FreeBSD in
similiar situations:
strip(1) - discard information from ELF objects
disc, if_disc(4) - software discard network interface
edsc, if_edsc(4) - Ethernet discard network interface
ng_hole(4) - netgraph discard node type

I was kinda suprized to see strip come up....
