When you fuck your girlfriend so hard that your balls slap on her pussy
Her: I felt you Viking slap me.
Me: yeah my balls are sore from yesterday’s fuck.
When you fuck your girl in the ass while she’s on her period and proceed to pull out her tampon as you cum and slap her in the face with it, thus creating Viking like blood face painting.
Last night I ‘viking slapped’ Robyn and she looked like a true warrior!
