The space between a mans anus and nut sack. It is where a man is said to be welded together.
You can lick my weld if you like...actually just lick it anyway.
The seam of skin between the bullet hole and ball bag or vagina (minge, gash, clunge etc)
I'm gonna kick you in the weld
(Jamaica, old school) To engage in sexual intercourse.
I'm goin' to be weldin' her big time tonight, mon.
for sparks of love to fly
At raft camp, Josh and Lola were totally welding, you could see the sparks.
To rip a burning and horrible smelling fart
After eating that garlic pizza, I am going to weld.
