When one goes through one's entire house to get rid of any incriminating evidence after a house party, length of time without parents, etc.
I've been watching the house while my parents go on vacation for a week, so it's going to take a while to parent-proof my house. There are Tanqueray bottles in the fridge and Froot Loops all over the floor. I should probably also get the rolling papers out of the living room.
v. To hide any objects that you don't want your parents to see. Common objects to be hidden are drugs, porn, and condoms. You can parent-proof just about anything that your parents might see. Similar to girlfriend-proof
I had to parent-proof my room after I bought the Playboy magazines.
Verb. to make object or environment relatively mild and acceptable for contact with parents
Adj. acceptable from parents' point of view
My folks are visiting next weekend - I'd better parentproof my apartment .
"Dude, why would you add your mom as a friend on Facebook? Your profile isn't parentproof."
