Maria Cardona, Credible Cohen Testimony Has Trump, GOP Shook up. The Hill, Feb 28, 2019 ("opinion," as opposed to be a report).

(c) I wondered whether it should be "shaken up." I asked a librarian and she, at first flushed because she had not heard of it ("shook up"), changed her mind somewhat after a minute or two, thought it might be some sort of slang -- but could not explain.
(d) Firstly "English has at least 49 causative verbs." en.wikipedia.org for "causative."

We are familiar that in English, there are two categories of causative verbs: have, make someone do something (or have something done), plus allow, permit someone TO do something. In other words, the second verb -- after "somebody" is either the base form (or past participle) or the infinitive.
(e) However, the phrase "shook up" (to mean "shaken up") is different (and have a long history).
(i) shook (adj): "informal  (shook up) emotionally or physically disturbed; upset  <she looks pretty shook up from the letter>"

(ii)
(A) " 'All Shook Up' is a [1957 love] song recorded by Elvis Presley, published by Elvis Presley Music, and composed by Otis Blackwell."  en.wikipedia.org for "All Shook Up," which continues to say, "Blackwell wrote the song at the offices of Shalimar Music in 1956 after Al Stanton, one of Shalimar's owners, shaking a bottle of Pepsi at the time, suggested he write a song based on the phrase 'all shook up.' "  Yet some other sources says "coke," such as the next.
(B) All Shook Up

(f) At least in Ireland, "shook" (rather than "shook up") is enough.
(A) shook: "pale, ill, scared  <He was very shook looking>"
