Here comes someone who only ever talks to you when he needs a favor. Quick, parry! When you parry, you avoid doing things. As the needy friend approaches, say, "I wish I had time to catch up!" and hurry off. Or, hide under a table.
The word parry is often used to describe blocking or evading a movement, like parrying a punch, but it can also refer to an evasion that is verbal rather than physical. For example, if you are put on the spot and asked about something you’d rather avoid, you can parry to get out of it — change the subject or ask a question in return. When used in this way parry retains its sense of defending yourself through evasion.
