The spewing of jizz on your partner. Anywhere counts. The jizz itself can be defined as the splewage
I came inside my wife last night. As it leaked out she looked down and saw it she said "look at that lovely splewage".
A cocktail of bourbon, coke, and baileys Irish cream. Served over ice. It curdles when mixed, but tastes of rootbeer.
I had too many mud-ducks last night. Woke up with a nasty fucking hangover!
