When you have so much diarrhea that the toilet bowl fills up and the tip of your penis dips into the crap (usually by accident), so it has a nice even coat of shit on it when you pull it out.
Employee 1: "I felt like shitting all day long, but somehow held it... and when I finally shitted, I nearly flooded the toilet in milkshake consistency shit"
Employee 2: "Oh damn, did your junk touch your shit?"
Employee 1: "Yeah dude, I gave myself a Belgium dip!"
Cut the bullshit. When you on the road and you don’t have time to lay out a line of Columbian gold so you dip your dusty dollar bill straight into the bag and take a big whiff. You think you just hit a little toot but it hits harder than your mamma giving you a whoopin.
When you dip the dollar into the bag of blow and take a whiff. Thats the real Belgium dip
When a man stands naked over another laying down, head to tails, and pours a Belgium beer down his back soaking his balls and proceeds to tea bag them. Hence, a Belgiumdip.
