Cocksteer

Similar to cockblocking except this is where a friend steers your penis away from a vagina you most likely cannot get into and points it towards a vagina that actually does want your penis.

Mitch: Yo mang I'm gonna slam your sister tonight!
Kyle: Eww dude, she doesn't even want your penis. Maybe you should try going for my mom, shes been talking about you ever since she walked in on you in the shower!
Mitch: You're right, thanks for cocksteering me into your mom.
