the real definition of "splonking" is observing caves. Well think of that in the same sense but with a dirty mind. A guy observing or more a girls 'cave' is splonking.
So were you a splonker last night?
Yeah but as i was splonking, her mom walked in, which ended up causing her to sploosh in my face. it was delicious.

Walking around with no specific purpose. Often used as a time-killer.
Person: So what's up?
Splonk: Not much, just splonking for a while.
