'Jasenko', (pronounced Yaysenko) is an epitet, used to describe men with particularly sexy beards. Wisdom is best displayed by growing thick and luscious facial hair, hence, 'Jasenko' is also a mark of academical attainment.
No man, woman or beast can stand against a 'Jasenko', since a 'Jasenko' attracts all.
"Did you see that 'Jasenko' over there? Goddamn, by the look of his beard, I can tell he's a hit with the females here on campus.
Even I seem to feel a strange attraction to him, I mean, come on, look at his beard.
Who wouldn't be attracted by so much hair?
His total wisdom must be of gargantual proportion.
What an amazing young man."
