I bet she

“I bet she” is often used vaguely by internet microcelebrity/EX “OkayBuddyHetero” user CEO Of Simps (also known as Ceo, Ansari, Imsorry, and retard) to signal that he is currently thinking about a girl that he is romantically interested in. It is often used as a follow up to an existing comment by another person

“I bet she”
“I wonder if she”

Lizzgot: “Yo Imsorry my ass really hurts today”
Ceo: “I bet she”
This would signal that he is thinking about her ass now
