Diary sessions, sports trivia games, arena games and longs hours of chit-chatting made the highlights of day 19 of the ongoing Big Brother Naija Lockdown.

A major highlight of the housemates alcohol free night was Ozo and Nengi's conversation about erections. Nengi had dropped a comment about how men have 'conspicuous' erections unlike women.

Obviously caught up on the statement, Ozo began an embarrassing tale about his early morning erections and the one time her black outfit got it up. He recalled rushing to cover it with his hands and Praise advising him to leave the garden.

“It happened after I saw you change into that black outfit, the next thing ‘junior’ was up and Praise told me to go inside immediately," Ozo said.

Away from his surprising declaration, Ozo also beat the housemates to the Friday night arena games.

Ships in the house seem to be solidifying especially with Prince and Tolanibaj who seem to have moved from their Thursday night doubt clearing conversation to sleeping in each other's bed.

For someone who claims to not be interested in 'boy drama', Erica seems to be enjoying the attention from Kiddwaya at the expense of Laycon's heart.

Diary sessions are a huge part of the Big Brother Naija show and day 19 saw sessions with Nengi, Praise, Kiddwaya among others.

While Nengi seemed more curious about Big Brother's use of the word 'complacent', Praise admitted he was still not over being in the least voted housemate category from last Sunday's eviction.
