Sister Hopping

the act of flirting, expressing interest, having sex with, or dating one sister and then expressing interest, flirting, having sex with OR dating the other. Levels of interest don’t have to be the same for both sisters for it to be considered sister hopping. It is an extremely odd practice and one that neither of the sisters involved typically find flattering in the slightest.

Sister 1: oh my god, Alexander totally asked me on a date last night
Sister 2: oh no he didn’t! He has been flirting with me all WEEK!

Sister: oh my god! He’s sister hopping! GROSS!
