Juízo can mean 'judgment', 'sense', or 'sanity'. It's a common word, but its use here is particularly engaging.
In the song, the lyric "Tem um sem graça que me tira o juízo" translates to "There's a silly one that drives me crazy/makes me lose my mind." This phrase is a playful way of saying that one of her partner's smiles is so charming it makes her lose her composure or sanity, highlighting the intense effect of their love.
Get ready to fall in love with "Quatro Sorrisos" by Solange Almeida featuring Márcia Fellipe! This song is all about that head-over-heels, can't-get-enough kind of love. The singer is completely smitten, wanting to "aproveitar você, cada segundo que eu tiver ao seu lado" [enjoy you, every second I have by your side]. It's a love so strong, she wants to "te amar como se não houvesse amanhã" [love you as if there were no tomorrow].
What's really sweet is how she's memorized every little detail, especially her lover's expressions: "Já decorei seus quatro tipos de sorrisos" [I've already memorized your four types of smiles]. There's even a "sem graça que me tira o juízo" [awkward one that drives me crazy] and the one "depois do amor, me pedindo um abraço" [after love, asking me for a hug]. When they're together, it's pure magic – "a gravidade vai perdendo a força" [gravity loses its strength] and "quando eu te beijo até o relógio para" [when I kiss you even the clock stops]. It's clear that "o nosso amor já 'tá fazendo mágica" [our love is already making magic]!
