The implication of Victor being an undergrad in the novel is incredibly funny because, yes, it explains so much of his behavior and audacity, but it also means Victor's apartment could've been some sort of student housing, which means there were other undergrads living there, too.
Which means when Victor wakes up to the Creature standing by his bed like ☺️, and Victor freaks out and runs away, the Creature could have ostensibly wandered into the hallway after him, only to be met with a pack of incredibly drunk-after-an-all-night-1818-rager yet well-meaning frat boys.
Who were so blasted that they were just like, "Dude, what, do you play rugby? Holy shit, he's fuckin' huge, look at this fuckin' guy! Absolute unit!" And they all whooped and hollered and just ushered the Creature into their dorm to keep the party going.
And the Creature was just like, "?????" but very pleased to find other people vaguely shaped like him, so he lets them because he may be just minutes old but he knew early on all he really wanted was one (1) buddy and now there's, like, a herd of them and they're all having a blast.
When the guys inevitably pass out, sloshed beyond all sense, he just sits and waits for them to wake up and when they do, later that morning, he's poking at one of them to make sure the guy is still breathing, and the kid wakes up and yells for a second and squints at the 8 foot-tall (rugby???? player????) guy in their dorm and is like, "Shit, what is that?"
And another one squints at him and goes, "I don't fuckin' know, bro, but he can throw us so hard. Did you see how David just...fuckin'...flew out the window last night? Just hurled David like it was no big deal. That was awesome."
David groans and puts his head under his pillow because his headache is awful but he lets out a pained, muffled, "that was awesome" in agreement.
So in a rare case of wholesome frat boy camaraderie, this herd of college roommate boys, all of whom are dumb as rocks but well-meaning, just take the Creature in because, "There's this huge fucking monster guy and it's the coolest thing we've ever seen."
This would possibly mean the Creature is socialized to be a dumb-as-rocks frat boy, but because I cannot allow that to happen and because there is no universe in which he would not be into poetry, he somehow also gets socialized by liberal arts majors and is just as Sensitive™, it rubs off on his frat buddies, who start saying things like, "No, man, it's Sturm und Drang, it's, like, the fuckin' vast rolling of the soul that, like...fuckin' eschews Enlightenment rationalism."
But some of the boys' lingo inevitably rubs off on the Creature so when, months later, Victor comes back to get all of his things with Henry post-mental breakdown, he bumps into a crowd of rowdy guys playfully jostling each other, and that crowd includes an 8-foot tall dude in a letterman jacket holding a volume of Goethe in one hand and a tankard of beer in the other, and he scoffs down at Victor and goes, "Accursed Creator! Why didst thou abandon me in my hour of need? Fuckin' lame."
And all his buddies go, "Yoooooo!" and high five.
