A girl, usually between the approximate ages of 19 and 30, of exceptional natural beauty, and who therefore causes 'wowsers in the trousers' of all men who lay eyes on her.
The male in this situation generally feels the desire for said lady to tease his weasel
, possibly squeeze the weasel (depends what you're into), please his weasel, and if all goes well, make the weasel sneeze.
**Not to be confused with chocolate weasel teaser**
Dave: Whoah! Dude, this city is full of weasel-teasers; I love it!
Boris: Yeah man...daaaymn! See that girl over there? She could tease my weasel
