The penalty kill occurs when there is more girls than guys (i.e. 5:4, 4:3). The penalty more specifically is the dumb annoying bitch that cock blocks the guys on the PK. It's a constant struggle to eliminate her from conversations and it's a team effort.
"Yo the girls such a bitch, looks like were on the Penalty Kill all night boys."
"Sandy was there last night cock blockin everyone, we were on the Penalty Kill all night. Dumb bitch."
