Mandle

a candle placed strategically in a man's room that, when lit, guarantees sex will occur

1. My roommate is sorely mistaken, he thinks girls like candles in the bathroom. Everyone knows that's not where mandles go.

2. Bro 1: She's coming over in five minutes, and we haven't cleaned up from last night's party! It looks like a frat house in here!
Bro 2: Quick, light a mandle! She won't notice anything else.
