The "up for nomination" really annoys me too (don't know how I forgot that one).
Speaking of nominations, a few years ago housemates started over-using the old "connection" reason, as in "I have not connected with X" and "he/she is the one I have the least connection with". I would like Big Brother to ban that as a 'valid reason'. But this series, I really became aware of how many housemates, when nominating, began every sentence with "I feel like ...." (or in dear Cristian's case, "I fee-oo laaaaaaak" - sorry, Cristian - I actually wanted you to win!).
