Spot Weld 

When a loser who has little to no contact with girls finally gets touched by a girl or a stripper and immediately blows a load in his pants but says nothing.. Then said load dries and his junk is stuck to the front of his pants...

We got Chuck a lapdance at the strip club lastnight and he totally spot welded himself to the front of his pants during the dance.

Harp had never been with a girl before, when she took her top off it caused him to spot weld himself to the front of his pants.

Spot-Welding
