The episode is "The Good Son" (125). Here's the scene:
Eric and Donna are making out on the couch. We hear Bob and Midge arguing from outside.
MIDGE: Here's a crazy idea: why don't you do the dishes, Bob?
BOB: Why don't I do the dishes? I work all day!
Eric and Donna stop kissing.
MIDGE: Well, I meditate all day!
BOB: Why don't you meditate over the sink and wash the dishes!
Bob and Midge come in. Eric and Donna move away from each other.
MIDGE: Donna, will you tell your father he's a jackass!
Bob pours a glass of Scotch.
BOB: Donna, your mother was fine until she met those feminists and started thinking!
MIDGE: Well, excuse me, Bob, but I'm not happy!
Midge leaves the room, crying.
BOB: Really? Really? Well, I'm ecstatic!
Bob turns to Eric.
BOB: You better watch out, Eric, ‘cause it's all fun when you're making out on the couch, but then they get bigger and bitchier!
Bob looks at Donna
BOB: Hey, no offense, honey.
Bob looks at Eric and nods as an affirmation of his warning; then he leaves. Donna looks on the verge of crying.
ERIC: You're not gonna get bitchier, are you?
DONNA: Shut up!
ERIC: Oh, no.

I totally understand why Donna was upset after that. Her parents are fighting really badly. Her father's chauvinism comes out full force, and he essentially said Donna's going to become a bitch. How nice.

Bob does something similar in "Red's Birthday" (210) when he and Midge write nasty things to each other on a paper posted on the fridge. I think Midge had written "Jackass!" and Bob wrote, "Bitch!" The scene then goes as follows:
BOB: Donna, I don’t want you reading this!
DONNA: Dad, Hyde’s here!
BOB [to Hyde]: Well, you can read it because you’ll appreciate it,
[to Donna] but not you!

Bob halfway knows his behavior isn't good for his kid, but he's just so un-self-aware.
