Panel 1: Now that Gordon has to take his dad's ride back home, he observes that he and Mike didn't manage to find female companionship. Mike says that it was a good night anyway.
Panel 2: He then says that there's nothing out like a night with the guys anyway because guys are solid. As by way of example, with guys, one does not have to play the game called "having to understand that feelings he cannot experience are actually real." There is not the hassle of having to speculate that "your insulting Valentine card hurt my feelings and I don't actually care what your hoodlum friends say to you and if you cared about me, neither would you" means exactly that. A guy can be himself: a belching no-life who'd die alone if it weren't for brain-damaged women eager to irritate and disappoint their mothers.
Panel 3: He then reminds us that he can never see a woman as a human being in her own right when he says that babes can make you feel great or like you're a bug and they're a windshield.
Panel 4: Gordon thought-bubbles that he's willing to risk that happening.
Summary: He doesn't realize that he has a girl assigned to him like some sort of incel fantasy. He also doesn't realize that he lives in a world where men aren't like any man I'd care to know.
