I have mild dyslexia and sometimes transpose letters in a word, even leave some out.
At first I read this word and thought the definition would be "to try to emulate Britney Spears". I had to look at it again and see it was "ST" and not "SL" that started the word.
Come to think of it, she'd fit all three definitions anyway.
