Derived from the process of sheet welding (i.e. sticking two sheets together), refers to bed-based masturbatory activities, with the assumed consequence that the 'sheets' (substituted for 'blankets' for increased differentiation from the innocent metal-work activity), will be welded (i.e. stuck together with semen) together.

Doug: "No!"

Ash: "Don't lie, you're blanket welding again, aren't you?"

Doug: "Is it okay if I was thinking of you while I was doing it?"

Ash: "You're sooo not waking up tomorrow".

As the name implies, this is a weld that it brushed on. It is used by the 'clever' DIY'er to 'fix' holes in cars which would otherwise fail roadworthyness test. Brush on weld takes the form of either underseal or seam sealer. Since it is much easier to apply than a proper metal weld, in that it doesnt actually join any metal together, it is within the grasp of most spanner monkeys.

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.
