Chloe was rocking the Chloevage in that shirt earlier. Clark is going to have to superscrube his barn after Zod and Tess's freaky, angry sex. That scene reminded me a little of the Superman II Richard Donnor's Director's Cut where Lois fires a gun as Clark to force his hand. Clark should mind his own business.
It was green too so it probably had some meteor rock in it so it might cause sexual dysfunction instead.
What he's saying is, Chloe, is that Clark's got a mean cum-shot but not such a mean one to blow Lois' uterus out the top of her skull.
