DD (15) has a friend over.
As DH (not her dad) was walking past the table DD started saying "big dick, big dick" under her breath. Friend was in stitches. I was just about to tell her off when DP started saying "big tits, big tits" in the same way! .
Both dd and friend fell about laughing, DP looked furious and embarrassed. I said to him "why the hell did you say that?" and he replied "what, so she can say what she likes to me but I can't say anything back?" he's the bloody adult!?
