I draw your attention to the use of the word “something” to form adverbial phrases from adjectives in informal British English.
A few snippets from the electric intarwebs:
“It rained something dreadful last week and hence the marsh has had it annual top up.”
“ I had to post this, it had me laughing something awful, needed this today.”
Although, to my ears, it has the ring of informality, it has been around at least a century. OED has this in something, sense “2 c. Qualifying an adv. of manner. Also with adj. used for adv. in dial. and colloq. usage.”
The first entry that involves an adjective rather than an adverb is by that great recorder, George Bernard Shaw:
1898 G. B. Shaw You never can Tell in Plays Pleasant 211 Gentleman: Did you howl? The Young Lady: Oh, something awful.
