Seriously, I think "Always Sunny" explains it best (i.e., because of "the implication")
You can re-word most of Dennis' dialogue to fit the situation, too. "The implication that [she won't get an investment] if she refuses to sleep with me."
The last part of that clip is especially applicable. The other commenter sees this as a compliment. "She's attractive; of course she'd get hit on!" But it's a "compliment" with an asterisk attached to it, and the subtext is a massive power imbalance.
