When a male is straddling a woman's chest and she is preforming oral sex. The male poops on her and it slides down her chest. This works best when it is diarrhea.
Last night was so romantic. Joe gave me the gift of a California land slide.
The aftermath of a strong brewed Colombian coffee which results in a stomach-clearing shit-storm. This poo is not like any regular, solid poo; rather, it is a slimey, smooth, and smelly production. Post Colombian Landslide, one may feel 10-20 lbs lighter, happier, and healthier.
"Don't use the bathroom for a while, I had some Chipotle last night and just had a Colombian Landslide in there"
"My stomach hurts, I think I should have a coffee and induce a Colombia Landslide"
When you accidentally shit yourself and it slides down your leg. Most common when exerting oneself while performing a seemingly easy task. e.g. drinking a glass of water with one hand. Usually used as an exclamative.
