Something or someone full of life, mediocre with the ladies or men in fact its quite hard to tell what this person wants. Be cautious though, from time to time they will see it in their best interest to stab you with the "Full"ness of the "grabe" aka tell on you. Don't bother cleaning up anything near it either, it all just gets messed up in the end since a Fullgrabe has a lack in sense of hygiene. Poor social skills and definitely a poor sense of humor.
That guy is so a Fullgrabe
