Changing lanes without signaling

It's when a man goes from the vagina to the anus in one quick motion without warning his partner.

I was changing lanes without signaling on Renee in the shower and she went deaf for a minute.

changing lanes without using your signal

When you go from vaginal sex to anal sex without warning the girl. Must be done in a quick fashion.

Jake : Hey did you end up changing lanes without using your signal on that chick last nite?

Steve : yes sir. she said she didnt like anal but she got it anyways.
