look up any word, like the eiffel tower:
 
1.
A raised mark on the skin (as produced by the blow of a pecker) Could result in a abrasion, contusion, swelling, or other bodily harm.
Damn, check out the pecker welt on Shariqua's cheek, her and Ray Ray must be back together.

2.
The raised, slightly bruised outline of a penis left on your lovers forehead.
eg. "check out the peckerwelt on that whiney biznitches forehead!"
