A borderline sexual, flirtatious act where the girl in a
relationship instigates a playful wrestling match with her boyfriend, usually ending in the girl on top of the guy with his arms pinned on the whatever surface the couple
may be wrestling on, i.e. the floor or a bed. The couple
may proceed to engage in other romantic activities such as kissing or sex.
I was about to get undressed when all of a sudden
my girlfriend wanted to tussle. She tackled me on the
bed and got on top of me. I couldn't really do much because my arms were
pinned above my head but it was sexy.
