Welcome to yet another FASCINATING Mathews County language lesson.
When someone SWELLS UP, they are COPPING AN ATTITUDE. Gettin' huffy. Pissed off. Upset.
There are various forms of the verb "swell," some of which, like SWOLLED, have not a hint of being in the ballpark of grammatically correct, but the point is that when someone's swelled up, it's so bad that no rules apply.
Daughter: "Hey, Daddy, where's Mumma?"
Father: "I dont know. She's all swelled up."
Daughter: "What's she swollen up over?"
Father: " Who the he** knows. All I did was (insert any Man Activity of your choice here that would have nothing to do with being a helpful partner to his spouse) and now she's not speaking to me. She's SWOLLED UP I tell ya."
Being SWELLED (or swolled) UP is contagious. In the scenario above, the Father inevitably becomes swollen. Or swelled.
And the Daughter exercises extreme patience until all parties DEFLATE.
