No period like, "Oh shit! Am I the only one you sleepin' with?"
"Am I the only one you sleepin' with?"

from Childish Gambino – You See Me Lyrics on Rap Genius

Meaning

Missing a period can indicate that a girl is pregnant. In that situation, this might be Gambino’s response.

Him saying the same line twice indicates two meanings for the same question. The first time asked is Gambino asking if the child is his, while the second time is Gambino realizing that if the baby is not his, the girl is possibly cheating on him.

Also, his response has no periods in it.
